TEXT: The apparatus is built according to principles developed by R. F. Rushmer et al. (Circulat. Res. v. 4,
1956, 684). A short ultrasonic impulse (0.5 microsec) is imparted to the organ and the time passage of this
impulse through the organ is measured by piezometers located counterlaterally. The ultrasonic carrier frequency
is 2.5 megacycles /sec and the impulse frequency is 1000 cycles/sec. The apparatus was tested on dogs with
induced aortic insufficiency. The accuracy of determination as well as the minimum measurable size depend
mainly on the ultrasonic carrier frequency.

Title : Investigation of the Dependence of the Dielectric Constant

Orig Pub : Zh. eksperim. i teor. fiziki, 1956, 30, No 4, 675-680
Ostract *. A method is described for the investigation of the dependen-
ce of the dielectric constant and the tangent of the dielec-
tric loss angle of barium titanate on the electric:field in-
tensity at various temperatures with the aid of a measuring
circuit, containing a linear variable capacitor, whose rotor
is driven by electric motor at 1.,500 rpm. During one half
of the period, the capacitance varies linearly, and during
the second half it diminishes. Over this cycle, upon suita-
ble choice of parameters, the circuit is -hfice in resonance
with the generator, and the resonance is fixed on the oscil-
logram in the form of two resonance curves. By connecting

Abstract : the tested capacitor in parallel the peaks of the resonant
curves are shifted by an amount proportional to the capa-
citance connected; the shift serves as a measure of this
capacitance. Heating of the specimen upon application of
a high field (up to 3.2 kv/cm) is prevented by the short ti-
me of application of thehigh frequency field (0.1 seconds).
The maximum error in the measurement of capacity is esti-
mated at 2%, an d in the measurement of the tai gent of the
loss angle at 25%.
The tangent of the dielectric loss angle is determined by
the method whereby the circuit is detuned as the voltage is
measured wiih a vacuum tube voltmeter.
It is shown that the non linearity of C = f (E), the tem-
perature behavior of the capacitance, and the tanFent of the
loss angle for barim titanate at high frequency and in strong
fields all have a character analogous to that observed in weak

Abstract fields. At a frequency of 1 Mc the capacitance is less and
the nonlinear properties are less strongly pronounced than at
a frequency of 50 cycles- In addition, the tangent of the
loss angle depends weakly on the field intensity. A mare
pronounced manifestation of the nonlinear properties of ba-
rium titanate in the region of the Curie point is attributed
by the authors to the fact that the rotation of the moments
under the influence of the external field is facilitated in
this region.

ABSTRACT: The authors investigated magnetic properties of the
following mixed ferrite systems3
nNiA1204 - lOONiFe2O4 (I) nCoA1204 - lOONiFe2O4 (II)
nNiMn204 - lOONiFe2O4 (III) nCoFe2O4 - lOOMnFe2O4 (IV)
where n = 0.51, 1,, 3i 5, 10, 15, 20, 30, 40 and is the
molar ratio. In these systems one of the components is
non-ferromagnetic (NiA1204, CoA1204 and NiMn204)i
except in the case of IV where both components are
ferromagnetic. Samples were prepared employing the usual
ceramic techniques; oxides or carbonates of "pure" and

annealed at 1380*C for two hours or at 14203C for one
hour. X-ray diffraction patterns showed that all
ferrites had spinel structure and were solid solutions
(Table 1). The following properties were investigated:
the temperature dependences of the initial permeability
~109 of tan 6 and of spontaneous magnetization;
the dependences B = f(H), and U =-f(H); the coercive
force and the Curie point. The concentration dependences
of p0 of the saturation magnetization B and of the
Curie temperature (0) are shown in Fig I and 2 for
systems I and II respectively. Fig 3 shows the
temperature dependence of the Q-factor of coils with
toroidal cores made of system I ferrites. Fig 4 gives
the temperature dependence of' Ii, for system Ill.
Fig 5 and 6 show the concentration dependences of lio,
of B and of 0 for systems Ill and IV respectively.
It was found that introduction of a non-ferromagnetic
component lowers the Curie temperature, reduces the

force. These results can be explained using the
theory of antiferromagnetism. For system IV ferrites
(with both components ferromagnetic) the law of
additive variation of properties with concentration
was obtained. The losses in all ferrites were due to
magnetic polarity reversal. There are 6 figures,

Solid Solutions of Niobates and Tantalateslof Transition
Elements Formed on the Basis of BaTiO 3 V1
PERIODICAL: Fizika tverdogo tela, 1960, Vol. 2, No. 1, PP- 73-79
TEXT: The authors examined niobates and tantalates of Mn, Co, and Ni
as well as their solid solutions on the basis of BaTiO 3* The samples
were prepared by the usual ceramic procedure. The authors prepared
compounds corresponding to the formulas AB 20 6 and A2B 207 (A = Mn, Co, Ni;
B -Nb, Ta) and their solid solutions ranging from 0-5 to 7 mole% InBaTW 3.The
dielectric constant of compounds of the types AB 2 06and A 2B207 within
the range of -195 to +1950C was found to be independent of temperature.
The quantities E and tan 6 are indicated in Table 1. The compounds
mentioned are not piezoelectric. Figs. 1-2 illustrate temperature
dependences of r for systems of the type BaTiO 3-AB206- Addition of more

than I mole% of AB 206 to BaTiO3 causes the piezoelectric properties of
barium titanate to vanish. Solid solutions of BaTiO 3 with pyroniobates
and tantalates of Mn, Co, and Ni (Figs. 3-7) differ greatly in their
properties. A strong shift of the Curie point toward lower temperatures
may be observed in all compounds of BaTiO 3-A2B 207under consideration
(Fig. 8, Table 2). All solid solutions of the systems BaTiO 3-A2B207 are
piezoelectrics. Some of them have hysteresis loops of a marked
rectangular shape and a non-linearity exceeding largely that of BaTiO 3*
A comparison of the electric properties of the systems under review
reveals that AB20 6-BaTiO3 and A2B207-BaTiO 3 differ very much in their
composition. It may be assumed that the addition of AB 206 to barium
titanate leads to structural deformations. This was established on the
basis of strongly blurred lines on X-ray pictures of the samples and on
the basis of a strong deformation of the samples after sintering (Fig. 9).
Presumably, this deformation may be considered to be the reason for the

disappearance of piezoelectric properties. On the strength of X-ray
analysis and the shift of Curie points, the authors detected the form-
ation of solid solutions of the second type in BaTiO 3-A2B207 systems
throughout the range of concentration. The results obtained here differ
from data published in Ref. 8 on the effect of barium niobates and
tantalates on BaTiO 3* Presumably, the differing properties of the
BaTiO 3-AB206and BaTiO 3-A2B207systems are due to the existence of
compounds of transition elements in the various compositions. The samples
were prepared in collaboration with L. Kolomiyets and Zh. Bichuch. There
are 9 figures, 2 tables, and 11 references, 4 of which are Soviet.

TITLE: Relaxation Polarization of the System SriI4 nMnO
PERIODICAL: Izvestiya Akademii nauk SSSR. Seriya fizicheskaya, 1960, Vol. 24#
No. 2, pp. 132 - 135
TEXT: The article under review was read at the Second All-Union Conference on
the Physics of Dielectrics (Moscow, November 20 - 27,..1958). In c ntinuation of
the studies made by G. r.- Skanavi and others concerning relaxation losses, the
authors conducted relevant investigations on ceramic samples of SrTiO 30 hNnO of
different compositions.This system was chosen in order to investigate the in-
fluenoe of manganese ions on the dielectric polaTization of strontium titanate.
MnC03 is dissociated on heating the atmosphere in KnO and C02 ; on further
heating, MnO is oxidized to "kurnakite", hausmannite, and other oxides. Hence,
the occurrence of relaxation polarization is to be expected in the presence of
ions of trivalent manganese in SrTiO,0 The composition of the samples in-
vestigated is given in Table 1. a and tan-?% were measured at 1-5 and 12 Ne/Dec

by using a Q-metor of the type KV-1 in a wide temperature range. Results are
given in two diagrams and a further table. Fig. I shows the temperature de-
pendence of a and tan2A on samples with 97 SrTiO 3 + 3 MnO at different fre-
quencies. The maximum of the temperature dependence on E in found to shift
toward higher temperatureswith rising frequency. The existence of this
tenperature maximum and its shift are indicative of a relaxation polarization
;.n this system. To clarify the structure of these samples, an X-ray structural
analysis was made, the results of which are discussed and given in Table 2.
Fig. 2 shows the temperature dependence of a and tan-aA in samples of the system
Bi2030 ano (n - 1,20). In this sjrstem, e is very strongly dependent on
temperature. Its values at three different t mperatures are given in Table 3,
as well as the values of tan?/g for the oompo:itions (100-n)SrTiO 3 -n(Bi203 AnO)
for n w 19 3, 59 and 10. In conclusion, it is stated that (1) the introduction
of manganese oxides into SrTiO 3 leads to the appearance of ionic relaxation
polarizationj (2) relaxation polarization also occurs in the system Bi 2030 nMnO,
in which the relaxation of weakly bound electrons is possible in consequence of

titanate with or without admixtures. The percentual content of admix-
tures in BaTiO 39 the Curie points, and the values of resistivity for the
compositions under consideration are specified in Table 3. It is noted
that the increase of electrical conductivity in the region of phase
transition is primarily due to a re-formation of the lattice and a
lowering of the conduction band. The electrical conductivity of solid
(Ba,Ni)(Ti,Zr)O3 and (Ba,Co)(Ti,Zr)O 3 solutions was studied between
260 and 500C within a field of 0.55 kv cm-1. The dependence of elec-
trical conductivity at 1810C and of the activation energy upon the com-
position is illustrated in Fig-3. It was found that in the system
(Ba,Ni)(Ti,Zr)O 3' the decrease of electrical conductivity in the region
of formation of solid solutions is related to the substitution of barium
ions by nickel ions. Substitution of barium ions by cobalt ions in the
system (Ba,Co)(Ti,Zr)o 3 leads to an increase of electrical conductivity.
A reverse effect of nickel and cobalt ions, observed by the authors, is

probably related to the fact that the electron shells of these ions are
filled (14i 2+_ 3d8; CO 2+_ 3d7). The thermo-emf was measured on the same
samples as the electrical conductivity. The coefficient of the thermo-
emf as a function of log I for the system (Ba,Co)(Ti,Zr)O3 is illustrat-
ed in Fig-3- It may be seen that the-relation a - A, - C log d (Fig.3)
which is well known for impurity semiconductors is valid in this case .
a is the coefficient of the thermo-emf+, a the electrical conductivity,
and A and C are constants. The value of C determined for (Ba,Co)(Ti,Zr)4
is similar to the theoretical value (200-4). In the case of barium
titanate and solid solutions of (Ba,Ni)(Ti,Zr)O 3? C is three or four
times greater than the theoretical value. The present paper was read
at the Third Conference on Piezoelectricity, which took place in
Moscow from January 25 to 30, 1960. Tge-re are 3 figures, 3 tables, and

platinum electrodes were fixed by means of cathode sputtering. The in-
vestigations were made within the temperature range of 50-2000C and with
fields of the order of 20 v/mm. The most important results of the mea-
surements are given in Tables 1 and 2. The "compounds" given in the form
"A 2B 20711 showed a break in the curve log d = f(l/T). The temperature

TEXT: This is the reproduction of a lecture delivered at the Third

a mixture of meta-compounds with oxides of bivalent metals and are called
11pyrocompounds". The nonlinear properties of the specimens were measured
at 50 cps with an instrument described in Ref. 6.at temperatures which
were about equally distant from the Curie point. The measurement results
are graphically shown in Figs. 1,2 and numerically compiled in a Table.

Position and height of the peaks of the F,(E) curves are greatly dependent
on the addition; BaTiO 3 - 11Ni2Ta20,11 has, e.g., for 0 and 1 mole% addition
about the same f,(E) curves, while at 2 mole%the maximum lies at smaller
E and is considerably higher, and at 3 mole%the F_(E) curve is
considerably lower, the maximum being small and appearing only at large E
,,alues. Fig. 2 shows the effect of additions upon height and position of
the maxima of the e-(E) curves. Investigation results are in good
agreement with X-ray and high-frequency experiments. It was found that the
tntrcduction of bivalent cations of transition metals causes the
tetragonality of unit cells to drop considerably and that the Curie point
is markedly shifted toward low temperatures. The greatest nonlinearity is
found ir) guch compounds as exhibit the least tetragonalities, i.e., those
with Ni2+ ions. Although the ionic radii of Mn2+9 C02+, and Ni2+ are not
differing appreciably, they still have quite different effects upon the
properties of solid solutions on BaTiO3 basis, which fact is explained
by the different filling of the 3d subshells of these ions. There are
2 figures, 1 table, and 7 references: 5 Soviet, 1 British, and 1 US.

TITLE: Investigation of the electric properties of some mixed
ferriteo in variable electric fields
PERIODICAL: Fizika tverdogo tela, v. 3. no, 2, 1961, 411-415
TEXT; Though ferrites are being more and more used in industry, their
electric properties, especially in solid solutions of ferrites, have been
insufficiently investigated, The electric properties of ferrites have
some peculiarities, as e.g. the high value of 1~, at low frequencies;
e decreases with increasing frequency. Whereas, the high 6-value and
its frequency dependence is explained by many authors by the kind of
crystalline structure, V. A. Ioffe et al. were able to show that tho
behavior of -the )t of ferrites does not depend on the crystalline structure
but is due to relaxation processes- As a contribution to this set of
problems, the authors investieated the temperature dependence ofE and
tang of mixed ferrites, the mechanism of polarization and dielectric
losses, as well as the dependence of 'these rharacteristic;s on the

produced in the same manner that is usual in semiconductor ceramics.
They had the shape of 1.5-2 mm, thick disks (35 mm diameter). The
temperature dependence of ~ and of tan,~ was measured by means of
Q-meters of the type V_F-5-1(KV-1) and VV-1,(UK-1.) between 20 and 2600C
and 10 6_ 10 7 cps. Measurements were carried out of some specimens also
down to nitrogen temperature, The cooiing rate was I deg/min within
the range of from 20-2600C. in the low tpmperature range 1.5 deg/min.
Temperature measurements had an accuracy of up to f 1.50C. The results
obtained by the investigations are all graphically represented. Figs. I
and 2 show E(t) and tanA = f(t) of the system (100 - n)NiFL- 2 04 - nCoAl 204'
Analogous curves were obtained also fcr orner systemse and tan

tan ~ increases with increasing n,. Also ele.-tric ocnductivity decreases
in all systems, with the exception of the aforementioned, with increasing
n. For the purpose of investigating the character of the losses,
tan6 was calculated by the formula tan ~ = 1.8,10 12 r3A f, and compared
with the measured values for the system-(100 - n)N-LFe2o 4 - '111iYM20 4'
The measured values at low temperatures (-- 8U'-C) are somewhat higher.
At low temperatures, the curves tan,4- = f(t) have a maximum, which
proves the relaxation character of the losses. A comparison of the
activation energies calculated from the temperature functions of i
and tan !J indicate that electron relaxations are concerned. This was
proved by direct measurements of log(tan--') = f(1 '/T). Thus, all result
confirm that the dielectric polarization and the losses of these ferrite
systems have relaxation character and are caused by ele--tron exchange
between 2- and 3-valent metal ions.. which are located in the same lattice
sites. There are 6 figures and 7 referen:~es: 3 Soviet-b-loc and

TITLE: Seignettoelectrical properties of SrNb 206-0.5 YbFeO
PEHIODICAL: Fizika tverdogo tela, v- 4, no. 10, 1962, 2971 - 2972
TEXT: A new compound showing at the same time seignettoelectrical and
ferrimagnetic properties was synthesizedi SrNb 206-0-5YbFeOY The
temperature of preannealing was 1100 0C, that of final annealing 1270 OC.
A proper choice of the final cooling rate is of great importance to
ensure the desired properties in the ceramic. The seignettoelectrical
state was verified by measuremer~ts of :-~(t) between -160 and +1600C and of
6(E) between 0 and 12 kv/cm, the magnetic properties by determining the
initial magnetic permeubility at 7-8 Vc/sec. This was equal to 5 at
room temperature. There are 2 figures.
