In condensed systems large-scale fluctuations describe: modifications of density in spatial domains, the linear measurements of which~by far oxce64 thedistance between particles; density fluctuations in spatial domains with linear measurements which are small .er than or equal to the average distance between particles,describe the "fine-13cale" fluctuations. A description of "large-scale" fluctuations is successfully accomplished by means of Hartree Is: (Khartri) self-consistent field. Basing upoh~a Hartree equation generalized for the case of non-steady dtates by Zyryanov (Ref 2) it is possible to describe .the short-range scattering of particles as a source of momentum-interaction.

The influence of. paramagnetic re- sonance on the optical effect is based upon spin-orbit inter- actions. The dielectric constant characterizos the optical properties, and as the state of the sp in system varies con_~ siderably within range of paramagnetic' iononiincet a change of the state of the spin system (in consideration of spin- orbit coupling) leads to a variation of the dielectric con- stant, which fact explains the influence exercised upon opti- cal properties.

ExPiton energy and the connection between exciton-phonon interaction and the internal state of the exciton was investigated for strong coupling by S. 1. Pekar and I. M.

The authors of the present paper consider excitons to be elementary excitations in a multi-electron system, which interact with the lattice.

The presents authors attempt to set, up a quantitative -theory of, the: increase in the resistivity of ferroniagnetics in 6 radio-frequency field. Near the ferr~omagrietic resonance, the energy of the radio-frequency field is transferred to spin waves having a wave number close to zero and~ihis corresponds to an increase in the precession angle.'.of!.:the magnetization vector. Since in this case.the magnetization remains uniform, there:is no additional: contribution to resistivity. However, in~the case,of:a ferromagnetic metal in a radlo-frequency fleld, the magnetization in the skin-layer A~illlno longer be uniform and the radio-frequency -field will tend to increase this nonuniformity and excite a spin wave.with a-wave number k-v.l/6, where .6 is the:depth of the skin-layer. This increase in thenonuniformity of the :Magnetization in the skin-layev nea~r r-esonance will give rise~to an additional interaction-of conduction electrons with the metal and hence the resistance of the skin-layer has a resonance Card 2/3 character.

Moreover, the analysis:includes only terms which are of the first order in the amplitude of the radio-frequency field ho so that the amplitude must be considerably smaller than the width of the ferromagnetic resonance line. It is shown that the contribution to the resistivity due to this effect is given by Eq (27).

Increase of the temperature and the duention of annealing leads to decrouse of the temperature magnetic hysteresis. 4.
