TITLE: Magnetic Relaxation in Ferromagnetic Metals
PERIODICAL: Zhurnal eksperimentalinoy i teoreticheskoy fiziki, 1960,
Vol. 39, No. 3(9), pp. 726-736
TEXT: In the present paper, the authors calculate the ;agnetic relaxation
in ferromagnetics due to s-d-exchange interaction. They use a simplified
model of the ferromagnetic metal, which is based on the assumption of
two groups of electrons (conduction electrons and ferromagnetic electrons).
The relaxation terms are determined in microscopic spin-wave approximation.
The authors co fine themselves to the simplest case of a cubic crystal
(Fe, Ni), and i (parallel to the z-axis) is assumed to be so large that
the sample may be regarded as a single-domain crystal. First, the authors
derive expressions for He and Hd' which are the magnetic fields (due to
9-d interaction) acting upon the spin of the condu_qion electron and that
of the ferromagnetic iong respectively. For V - -AS9d one obtains
He = Asd/gsp and Hd = (3gsAQ/8gdgo)H. Proceeding from the spin

Hamiltonian of the conduction electron, the authors then derive the second
quantization Hamiltonian as veil as expressions for the energy spectrum
of the conduction eleotron and for the eriergy of the ferromagnon. By use
of the perturbation theory the authors study the variation of the ferro-
magnon distribution funotion n(f) in time. The double absolute value of
the sum of projections of all d-spins is expressed by L, and L gives
the equilibrium value of L. dL/dt and An(f) are obtained wid
L0-L - 2 2:An(~) and IL c-LI/L 04r, 1. The fact that the spins of the con-
f
duction electrons and the ferromagnetic spins interact not only with each
other but also directly with the lattice is taken into account in the
following. A number of special cases are calculated. The relaxation times
Tad and Tds' which are defined by formula (29), are finally estimated for
iron by means of the experimental value of the number of magnetons per
iron atom (2*22)o Thust one obtains

ABSTRACT: The Hamiltonian interaction of conduction electrons and magnons is
analyzed by the Green function method. The solution of the Dyson equation in the I
first approximation of the perturbation theory provides the magnon spectrum,
taking into consideration the sd':4nteraction. The error is a conventional conical
singularity. No comparison is made with other results. Yu. Irkhin. [Translation

ABSTRACT: The article is a study of the change in the characteristics
of the phonon spectrum as a function of the magnetic field. This change
is particularly marked with strong magnetic fields, since the change in
the Fermi surface in this case is considerable. The calculation Is
carried out by the known method of Green's functions at a temperature of
absolute zero. Practically speaking, it is a question of temperatures
much lower than the electron degpners.cy temperature and the Debye
temperature. To find the pbonon spectrum, a solution is found to the
Dyson equation for the Green's function of the pbonon

la frefa volume of a superfluid liquid is larger in -the pores than in
the f:me volunye. Similar effects can be observed also in a partition
jwith minute pores separating two values of a superfluid liquid. It
!is pointed out that this increase is connected with the propagation
;of the wave field of the condensate to neighboring regions, and is
~Bimilar to the Josephson effect in superconductors. The difficulty
.1connected with the need for taking Into Account the complicated
_-~boundary conditions is circumvented by averaging the wave function
