[en] The spin dynamics of paramagnetic impurities in a superconductor in the presence of external magnetic field is studied both theoretically and experimentally. The spectrum simulation with involving the mw energy absorption by unhomogeneous spin-wave excitations gives a satisfactory description of these dependences. The spin stiffness coefficient and temperature dependence of lanthanum spin susceptibility are determined

[en] A study was made on abnormal properties of monocrystalline LuRh_1.2Sn₄(I), namely: specific electric resistance ρ in 2-300 K range at different values of magnetic field, as well as the effect of Gd magnetic impurities on ρ. It is shown that ρ temperatire dependence is of nonmetallic character; magnetic field H ∼ 55 kGs at T > 10 K doesn't affect ρ of pure I. This testifies to nonmagnetic nature of observed anomaly. Introduction of paramagnetic Gd impurities to I supports the presence of localized and interference effects in I monocrystal. 5 refs.; 2 figs

[en] Li alloys with doppings of Zn, Cd, Al, Bi and Sn are investigated by the method of paramagnetic resonance on conduction electrons. The dislocation contribution to the spin scattering of conduction electrons is found. Thermodynamical parameters of the processes of solUtion of Al, Bi and Sn in Li are calculated, the binding energy of Sn and Al atoms with dislocations in Li is found

[en] ESR on localized gadolinium moments in Y_1-xGd_x and La_1-xGd_x alloys in 0.2≤x≤1 concentration region is investigated. Parameters of exchange interaction and crystal field conductivity electron spin scattering rate in the lattice inhomogeneities and in the phonons are determined. Reasons for nonmonotonous behaviour of these values depending on magnetic ion concentration are analysed

[en] Effect of uniaxial stress on the EPR spectra of Er³⁺ ion impurities (0.04 at% Er) in copper single crystals was investigated at T = 1.8 K. A g-factor anisotropy was observed. The comparison of the point charge model values of the spin-phonon coupling constants with the experimental one testified to the validity of the qualitative interpretation of the effect observed and to the insufficiency of the point charge model for a quantitative calculation of the crystal field in the Cu:Er system
