ABSTRACT, By an auxiliary internal parameter the author understands
a quantity which describes an internal property of a system
and is a function of state under eauilibrium conditions,
When the system is perturbed the return of the aux-iliary in-
Uernal parameter -q to its equilibrium value produces a lag,
which appears as an inelastic effect: internal friction and
absorption of sound. Internal friction may occur in systems
where 71 is the degree of lonc--rancre order (Refs.1-5), in
1'
substitutional (Ref.3) and interstitial (Ref.6) solid solut-
ions, where -q is the degree of the predominant, distribution
of atoms -produced by deformation, Internal friction may occu
also in antiferromagnetics where i1 is the degree of anti-

ferromagnetic order. Internal friction can be er-pected also
LD
in ferroma-neties, ferrites, ferroelectrics and piezo-elect-
rics, in which -q is, respectively, the spontaneous magnet-
ization, sDontaneous and forced electric polarization. In
internal friction occurs in systems with an auxil-
iary parameter whose change is accompanied by perturbation
of the system and in which perturbation of the system alters
the value of the auxiliary parameter. On propagation of
sound in a system with an auxiliary internal parameter, local
variations in the state of the system will produce relaxat-
-ional absorption of sound,since the system as a whole will
pass through non-equilibrium states. Such absorption of
sound occurs in liquids and in multiatomic gases. The author
calls acoustic absor-otion in solids - internal friction, and
acoustic absorption in gases and liquids - absorption o~ sound.
The paper gives a thermodynamic theory of internal friction
and relaxational absorption of sound in systems with auxilia-
ry internal parameters, Formulae are given for the magnitude
of internal friction and values of the velocity and the co-
efficient of absorption of sound in such systems. Near the

ABSTRACT: The present work shows the following: Using the thermo-
dynamical method of irreve-.'sible processes equations for
the time change of the magnetization taking into account
the spin-spin relaxation and the spin-lattice relaxation
can be obtained on very general and simple conditions .
Furthermore the influence of the spin-lattice relaxation
on the phenomena of ferromagnetic resonance are discussed.
The system of spin-moments responsible for the magnetic
properties of the ferromagnetic substances can, from the
thermodynamical point of view of be separated into on own
sub-system with the temperature T(spin-system). The

here considerad analogously to the thermodynamic theory
of paramagnetic relaxation (K~ Gorter, Ref 4) as a
thermostat the temperature T0 of which is in this work
regarded as constant. It can be shown that the last
mentioned condition will only slightly become manifest
in later given conclusions, and one can also easily free
oneself of this condition. The processes of the spin-spin
relaxation and of the spin-lattice relaxation in general
take place commonly, and they are also connected with each
other. In the case of a sufficiently fast change of the
field strength f? the sub-system of the spin moments will
be in e non-equilibrium state. The temperature T of the
sub-system and the magnetization M do not satisfy the
equation of state. In order to take into account the
internal relaxation the author puts down an expression
for the change of the entropy of the non-equilibrium state
of the subsystem:

is found. An equation describes the time modification of
magnetization which is dependent on the gyroscopic
properties of the magnetic moment and the process of the
spin-spin relaxation. The characteristic feature of the
isothermal and adiabatic changes of state are shortly
shown. Then an expression for the amount of heat do,
is put down which is transferred from the spin system to
the lattice during the time dt. The specific heat of the
spin system is so great that a radiofrequency field with
small amplitude cannot noticeably raise its temperature.
Therefore the spin-lattice relaxation has only an un-
important effect and practically escapes observation. The
spin-lattic relaxation is neglected in the further con-
siderations. At temperatures far from the Curie point

ABSTRACT: Postnikov (Refs 1, 2) proposes a theory of internal
friction in metals at high temperatures. According to
Postnikov internal friction is due to directed migration
of vacancies in a field of stresses produced by extension
and torsional vibrations of the sample. The present
author criticizes in detail Postnikov's formulae, for the
following reasons. (1) Postnikov assumes that a uniform
elastic stress a in a sample (due to the weight of the
system producing torsional vibrations) both lowers and
increases the energy of formation of vacancies Ull which
is impossible since in this case only one effect may occurg
either an increase or a decrease of Ul (cri is a,scalar
component of a tensor). In addition to this erroneous
assumption, Postnikov takes the equilibrium number of
vacancies n t- be given by

SOV/139-59-3-28/29
On the Papers of V.S. Postnikov on the Theory of Internal Friction
in Metals at High Temperatures
The mechanism suggested by Postnikov for internal friction
due to motion of vacancies is physically inconsistent.
It is known that directed motion of vacancies in a field
of elastic stresses is possible only when that field has a
gradient, For the above two reasons, Postnikov's formula
for the amount of energy scattered by elastic vibrations
in a sample, given by Eq (1), and his formula for internal
friction, given by Eq (13), are both in error. The
physical meaning of the coefficient of proportionality a
which is very important in internal friction, is not given
at all. (3) kt the end of his second paper (Ref 2)
Postnikov discusses relationship between the rate of
diffusion creep and internal friction. Here again the
same error is committed: forced diffusion of atoms is
considered "in the direction of action of Ci stresses"
and such diffusion does not in fact occur. It is known
that forced diffusion of atoms in that sensa can be
produced only by a gradient of elastic stresses and not by
Card an elastic-stress field itself. It follows that

friction in metals at high temperatures is related to
vacancies but an interpretation different from that of

Using this expression, it can be shown (Refs 1, 3) that

does not include the contribution due to ferromagnetic
order, ca and k,-, are the specific heats, and cla
and cl, are the specific heats not including the
effect of ferromagnetic order. Since the ratios of
the moduli and the specific heats are close to unity,
Eq (4-) may be replaced by Eq (5), where WET)" is
the contribution of the ferromagnetle order to the
magnitude of the reciprocal of the isothermal Young's
modplus. The second term in Eq (5) is of the order of
.10-4 and hence the degree of relaxation will be
determined by the first term only. It is clear from
Eq (3) that -when W-tcS = 11 the absorption of sound will
have a resonance character. The degree of relaxation of
the isothermal Young's modulus can be expressed in terms
of the degree of ferromagnetic order using Eq (6) which
was obtained by the present author in Ref 10, where c"a
is the additional specific heat due to the existence
Card of ferromagnetic order. Using the Weiss theory (Ref 3)~
2/5 one has Eq ( 7) , and hence Eq (8) , where G) is the Curie
temperature, k is Boltzmann's constant7-and N is the
number of uncompensated spin moments per unit volume . L4/

Relaxational Absorption of' Ultrasoni-- Waves in Ferromagnetics
As can be seen from Eq (8), the degree of relaxation,
and hence the absorption of sound at frequencies given
by #,WES1 increases with increasing temperature and
reaches a maximum at the Curie point at which Eq (9)
holds. If the ferromagnet is placed in an external
magnetic field H, then instead of Eq (7) one has
Eq (10) (Ref 3), where & is the Bohr magneton.
Hence, using Eq (6) one finds that in this case the
degree of relaxation is again given by Eq (8) but now
the degree of ferromagneti,3 order is a function of the
external field7 and hence the degree of relaxation is
determined not by the spontaneous magnetization but by
the true magnetization. However, the increase in the
magnetization due to the external field is small and
does not play an important part in a wide range of fields
and temperatures. The effect of the external field
need only be taken into account near the Curie point.
The shortcoming of the Weiss theory is the fact that it
Card neglects ferromagnetic order at short distances. if
3/5 this approximation is removed,, one obtains (Refs 3, LO
instead of Eq (7) the expressions given by Eqs (11) and

TITLE: The Mechanism of Formation of an Impurity Peak of
Internal Friction P
PERIODICAL:Fizika metallov i metallovedeniye, 1959, Vol 8, Nr 6,
pp 829-833 (USSR)
ABSTRACT: In polycrystalline pure metals only one internal friction peak
is observed at high temperatures. Since such a peak is
absent in monocrystals of pure metals, its appea a
ascribed to relaxation at the grain boundaries.1v hen
impurities are introduced into pure metals, an additional
internal friction peak appears; it is known as an
impurity peak. From the systematic investigations of this
impurity peak, carried out by several workers (Ref 1 to 5),
the authors draw the following general conclusions:
(1) Even small amounts of impurity (0-03 atomic %. Ref 3)
may produce an impurity peak of internal friction.
(2) On increase of the impurity concentration the impurity-
peak height generally rises but in certain alloys it
reaches a maximum and then falls or even disappears
completely (Ref 6) at higher impurity concentrations.

SOV/126-8-6-4/24
The Mechanism of Formation of an Impurity Peak of Internal Friction
responsible for the impurity peak is close to the
activation energy of diffusion of atoms, provided the
impurity concentration is sufficiently great.
(4) With increase of the impurity concentration the
internal friction peak due to relaxation at the grain
boundaries (observed in pure polycrystals) is depressed
and may disappear altogether (Ref 1 to 3, 6).
(5) The impurity peak is found only in polycrystals and not
in monocrystals and consequently, just like the peak
observed in pure polycrystals, it is due to processes
occurring at the grain boundaries.
(6) The magnitude of the impurity peak is only slightly
affected by the change in the mean grain dimensions (it
falls gradually with increase of these dimensions; Ref 3
and 6). In contrast, the relaxation time related to the
impurity peak depends strongly on the mean grain dimensions,
rising rapidly with increase of the latter. The
experimental observations summarized in the above six
points can be explained as follows. Impurities are
concentrated predominantly at the grain boundaries becaus

the grain boundary than inside the grain. Elastic
deformation which alters this distortion energy would
either favour or obstruct accumulation of impurity atoms
at the grain boundaries. Consequently if such
deformation is varied periodically the impurity atom
concentration at the grain boundaries will also vary
periodically. If elastic deformation alternates
sufficiently rapidly the changes of the impurity
concentration will not manage to follow elastic
deformation and this will, of course, lead to dissipation
of elastic energy, ie to an impurity peak at appropriate
frequencies. The authors discuss this mechanism
mathematically and show that it explains satisfactorily
the experimental data summarized in the points (1) to (6)
above. The paper is entirely theoretical. There are

ABSTRACT: This work was carried out in order to study the structure of ZnSb-CdSb
films and the relation of electrical conductivity to temperature in this material.
I
These thin films were vacuum-precipitated on a series of cold glass, chemically
cleaned plates. The electrical conductivity of the precipitated metal layers
was measured in air with the use of a MVU-49 bridge and a M14-4 megohm-meter. The
results obtained are presented in Fig. 1 and Fig. 2 of the Snelosure. It was
established thatt 1) the relation of electrical conductivity of films to metal
concentration was similar to that of massive polycr7stalline samples; 2) in all

the varieties of metal concentration studied here., electrical conductivity in-
creased with the increase in temperature; 3) high conductivity observed in the
1,.,-samples rich in CdSb was explained by a partial decomposition of this compound
(during the precipitation process) into the components Cd and 5b; 4) the electron
diffusion patterns obtained immediately after the metal precipitation had diffused
lines-
this was explained by a certain degree of structural disorderliness (the
lines became well defined again after the samples were heated at 120-150C for 30
min); 5) the structure of thin films was of the type ZnSb. The lattice parameters
decreased with the increase in ZnSb concentration; 6) the structure of CdSb was
studied in order to check the possibility of its decomposition (into Cd and 5b)
during precipitation. No lines corresponding to Cd or Sb were observed. Orig. art.
