ABSTRACT: The authors stndy the paramagnetic properties of trivalent neodymium and
cerium impurity ions in Cie ttuigstates of strontium and calcium. The measurements
were made at 4.20K and a frequency of 10 Gc. The electron paramagnetic resonance
spectra indicate that the overwhelming majority of the lanthanon ions am magnetical-
ly equivalent and are located in a uniaxial (apparently tetragonal) crystal field.
The spectral parameters for the impurity ions are tabulated. A comparison of the re-
sults w1th previously published data shows that the tetragonal centers of the Nd3+
and Ce3 ions in CaW04 are faithfully reproduced in spite of wiGe differences in the

conditions under which the crystals were grown. A transition from CaW04 to SrW04
causes only a slight change in the g-tensor of the same ion, so that all spectral
data may be referred to centers of the same type. Anisotropy in the g-factor for
trivalent neodymium increases with a transition fTom calcium to strontium tung
The reverse is true for the Ce3 g-tensor. The authors are grateful to A. M. 210

of the EPR spectrum of the CaW04.-Sm:Nd specimen indicates that the major axes of the mag-

nominally ne er cent of Dy. At (1c, and 14.2K, the EPR spectrum

contains predominantly of one broad intense line, accompanied by the

the temperature Is reduced to 1.6K oo that thin line can be attributed
to the ground state doublet of the Stark otructure of the 6if 15/2
level. The line position can be described by the usual axial spin
Hamiltonian with S = 1/2., for which the conntants are given. In-
~creasing the frequency to 10 Gc not only broadono the already exist-
ing linen but leads to the appearance of new linen, some of which
decrease in Intensity on cooling to 1.6K. Additional research is
necescary to explain these features of the spectrum. Orig. art. has:

ABSTRACT: In view of the lack of data on the crystal-line field acting on the TR3+
ion in the lattice of scheelite (CaW04), the author has investigated the EPR of
NP'~ and the variation of its magnetic properties in six hoste with general formuU
Me(W, Mo)04, namely Ca!,;O.S, CaMoO4, SrWO4, PbMoO4, BaWO4., and BaM04. The experi-
ments were made at 4.2K using video spectroscopes for the 3- and 10-cm bands. The 1;
g factors and the hyperfine structure constants were determined. The results show
that with increasing crystal-lattice parameters (on going from CaWO4 to BaMo04),
9 decreases rapidly but g remains practically constant. This indicates that the

magnetic centers are all of the same nature. The g-factor variation ia*alwst line-
ar. The results can be reconciled with theory if it Is asavned that the crystal-
line field is close to cubic. From the g factors and the hyperfine structure con-
stants the author estimates the form of the wave function of the principal doublet
and the admixture of states with spin J ~ 9/2. It is suggested on the basis of thei
results that the cubic part dominates over the axial parts in the potential of the
tetragonal centers in sheelites. The author thanks L. Ya. Shekun for useful ad-
vice. Orig. art. has: 3 figures., 2 formulas.. and 3 tables.

ABSTRACT; The ESR svoctrum of Nd Y ions was studied in Ba:~oC4 single c!7stals grown
from a solution Ball the ions wore magnetically equivalent; their

sDectrum is described by a !ip-in 11VAltonian of axial sy=otr7. In the orientation
07= 900 (0 being the angle between the magnetic field and tho c axia of the crystal),
the measurements were made at a frequency of 10 XMc. As the orientation 0 = 0 was
apDroachad, the lines broadened sharply, and the spectrum shifted to high fields. FQr!
this reason, measurements in the orientation E) = 0 were performed at a frequency of
3 rxia. However, even at this frequency, the hyperfine structure could not be observed!
because of the large width of the lines, and only the value of g was obtained. Tho
lamiltonian parameters which could be determined were as followsl 1.

ABSIVCT: The authors determined the parameters of the spin Hamiltonian describing
the EPR of Nd3+ contained in single-crystal CdJ4o04. The samples were prepared by the
Czochralski method. The values of the constants obtdined at 4.2K and -9.4 GHz are
listed. By comparing the results with data obtained for other Gchcelites in an
earlier paper (m v. 8, 731) 1966) it is concluded that the parameters of the
+
Hamiltonian of Nd3 in CdMoO4 obey the same laws that characterize all other schee-
lites, namely a smooth dependence on the lattice constant c. In particular, extra-
polation of the curve for the g-ractors in the earlier investigation yield excellent
agreement with experiment. To decide conclusively that the regularities observed are
'universal, it is necessary to carry out experiments with Nd3+ in SrMoO4 and FbWO4.

T E X T rhis paper in concorned with spin waves in a syst*0m or
CLoctrons with an arbitrary dispersion-law and ferro-, ferri- wid
antiferroirtagnetic spin order. The theory is developed using the
method for describing collective excitations in a system of
electrons (excitons and plasmons) as desc*ribed by C. Horrie (Prog.
Theor. Phys., 1959, 21, 113), K. Sawada (Phy8. Rev., 1957, 1o6, 372)
and K. Sawada et al (Phys. Rev., 1957,. 1a8, 507). The first
section of the paper is concerned with the ferromagnetisin of a
system of electrons with an arbitrary dispersion law and a positive
exchange integral. The Hamiltonian is assumed to be of the form:

interaction matrix element. The ;,-cctron energy thus turns out
to be dependent on the spin orientation. It is then assumed that
states with uncompensated spins are available and collective
excitation-9 associated with spin flip are discussed. It is
shown that the particular feature of the collective model is that,
in general, there are ~ nondegenerate spin-wave branches, where
6 is the number of states with uncompensated spins. This
splitting is of a similar nature to that for the levels in the
oxciton spectrum of semiconductors, i.e. the electron and the hole

forming the spin wave may be at various effective distances from
each other, giving rise to differences in the energy of these
spin waves. The second section of the paper is concerned with
ferri- and antiferromagnetism, in which the system is assumed to
consist of two sub-lattices with opposite magnetic moments. it
is further assumed that states with uncompensated spins.are
available in each sub-lattice. Only oxchange interactions between
the sub-systems are taken into account and the Hamiltonian is
assumed to consist of the sum of two terms, with the result that
there are two branches of spin waves. As before, expressions are
derived for the energy of the spin waves* The general conclusion
is that the main results of the homeopolar and phenomenological
models remain, except that there are* -f rather than two spin.-wave
branches and, in general, these branches are non-degenerate. It
is stated that the effect of the mobility of the "magnetic
electrons" (i.e. the fact that they are not localized at lattice
sites) on the temperature-dependence of the magnetic properties
of antiferromagnetics and on ferromagnetic resonance will be
.discussed in a future paper&

kF = 106-107 rOn = .106_1010 9ec_1 P which corresponds to the range of experimen-
tally observed values of ferromagnetic resonance line width. The indicated tom-
porature independence of the attanuation (and hence of the line width due to this
mechanism) is duo to the fact that the temperature spread of the Fermi surface
reaches 0.1 only near the Curie temperature. The second mechanism is the effect
of magnetic Interactions. It is shown that magnetic interactions can remove the
degeneracy In n of the spin wave spectrum. This splitting is-also independent
of temperature. It in pointed out that both mechanisms are very sensitive to
the structure and the degree of occupancy of the magnetic electron energy band
(which depend on the impurities). It ia concludod that the two meohanisma can
explain the large magnitude (about 103 oo) and the weak temperature dependence
of the forromagnetic resonance line width, but the abundance of parameters in the
theory makes quantitative comparison with experiment very difficult. The author

ABSTRAM The spin wave energy spectrum or an antirerromngnotic Iti a transverse
magnetic field is found on the basis of the cq~loctlvo electron model. It is
assumed that the system of magnetic electrons can be divided into two subsystems
cXand A with forromagnotic ordering of spins in each. Thu magnetic moments of
the subsystems in the a 'bsence of an external field are taken parallel and anti-
parallel to the z axis. The applied external magnetic field If is directed along
the x axis. The Hamiltonian of the system, considering exchange interaction only
between electrons of the different subsystems, in written in terms of

ABSTRACT: In order to determine the Influerce of the M91 frequency shift due to the
nuclear-spin and"?sPin-wave interaction at temperatures of the order of 1 - 10K on the
quadrupole splitting of the resonance line, the authors investigated the IM spectrum
in antiferromagnets with antiferromLq:nctism axes lying in the basal plane, with ac-
count taken of the quadrupole interaction. The nuclear excitation spectrum is de-
term.ined by a Greents function methofl. The transition from the spin operator to the
spin-wave creation and annihilation orerators in the Hamiltonian is by a rtandaid
procedure. On the basis of the theoretical calculations, certain general conditions
are deduced, under which the frequency chift becomes experimentally observable. These
conditions are that the parameter of the quadrupole interaction be appreciably larger
than the width of the resonance lin(-- to permit observation of the quadrupole splitting,

and that the interaction between the nuclear spins and the spin waves be sufficiently
strong. It is possible that CoCO3 ray be a suitable substance for such experiments,
in spite of its law Neel temperature (TN - 18K). The authors thank Ye. A. Turorv for
a discussion. Orig. art. has:- 27 formulas.

TITLE: The Operation of Thermal Power Stations in a System under
Variable Load Conditions (Rabota teplovykh elektrostantsiy

PERIODICAL: Teploenergetika, 1958, Nr 87 PP 3-8 (USSR)
ABSTRACT: The load curve of Mosenergo power stations has always
exhibited sharp peaks because of the large light industry)
domestic and traction loads. Until the Moscow-Kuybyshev
transmission line was opened in 1956, the base load was
mainly covered by thermal stations, which made up 85% of
the installed capa-lity. Small hydro-stations took some
of the peaks, and low- and medium-pressure stations were
unloaded at off-peak hours. When large imports of power
began to be taken from Kuybyshev, the conditions of
electricity supply in Moscow and the central regions
greatly improved. However, in order to avoid wasting
water at Kuybyshev, load had to be taken as uniformly as
ossible throughout the day to the Ifull capacity of two
Card 115 &00-kV transmission lines. Therefore, the load peaks on
the thermal stations became much more marked; moreover,

it was necessary to keep sets in reserve in case of failure
of supply from Kuybyshev. The overall ratio of maxim-_tm
to minimum load on the steam stations became about 2.4.
Many sets and boilers had to be started up to meet the
morning peak. Combined heat- and electric-power-supply
turbines, which formed about 26% of the total capacity,
could only be unloaded to the extent permitted by their hoat
loads; moreover, some stations had to burn excess gas7
particularly in surmner when the gas i3 less used for heating
and cooking. Finally, the Cherepet, station, because it
uses very-high-pressure sets of high efficient,,-y, was kept
on base load as far as possible. Therefore, on many
thermal stations, the ratio of maximum to minimum load was
up to 5, as indicated by the graph in Fig l.- In some cases
stations had to be kept loaded to maintain the voltage
in particular districts. When peat was specially plentiful,
peat-fired stations were kept running. Load curves of a
