The main ones are the following studies of the mechanisms and features of the relationship between spin current and spin dynamics in nanostructures magnet / antiferromagnet and ferromagnet / ferromagnet, as well as studies, changes in the magnetocaloric effect in nanopowders of perovskite, research La0.6Ag0.2Mn1.2O3 fields on optical liquid crystals with ferromagnetic and electret nanoparticles. The paper shows that the spin current through the interface depends on the reflection and scattering matrix coefficients at the interface. The electrically controlled magnetic switching of the antiferromagnet/magnet nanostructure with rotation of the antiferromagnetic states on and under the action of the effective spin torque in the interface region is described. In the model of strong coupling based on the method of nonequilibrium Green's functions in Keldysh's formalism features of spin torque effect in tunnel magnetic transitions with magnetic barrier layer and expressions for spin transport properties and torque taking into account features of spin-dependent electronic barriers. The magnetomechanical properties of the periodic structure consisting of magnetic stripes on an elastic magnetic film are calculated. The anomalous temperature dependence of the entropy entropy of La0.6Ag0.2Mn1.2O3 near the critical point was experimentally registered. The mechanisms of stability of the austenitic martensitic phase of Cu-Al-Mn alloys at different mechanical stresses and different temperatures are determined.
