R., Cheyshvili, Ojj, 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 Card 1/3 83769 Magnetic Relaxation in Ferromagnetic Metals S/056/60/039/003/024/045 B006/BO63 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 1 . 9 T 1 -F T 2-10 T 1n 4 - - 109 T ; these relations hold for ad 0.8+1.3-10- H ; ~ds Card 2/3 83769 Magnetic Relaxation in Ferromagnetic Metals S/056/60/039/003/024/045 BOo6/Bo63 temperatures from 2 - 30K to about 100 0K.

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 D-I(q. w) -i. D; 1. (q,6) n (q, w).

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 iover a volume containing sufficiently many pores.
