Diffusion, internal friction and coefficient of thermal conductivity for domain walls are computed. · Within the framework of the model of finite-gap elliptic potentials the Fermi surfaces of electrons in metals are calculated.. The construction of the two-dimensional non- separable electronic potential is offered on the basis of many-dimensional Weierstrass functions. The calculating finite-gap hyperelliptic electron potentials, energy spectra and wave functions is. · The analytical and numerical description of the basic state and tunnel phenomena of mesoscopic antiferromagnetic particles with nanometrical imperfections is offered. Ferromagnetic disclinations which are caused by screw dislocations in layered AFM and effects of tunnel change of topological charges and the destructive interference for magnetic imperfections are also predicted. · On the basis o f numerical accounts with the help of a method ALP waves in the approximation of complete potential (FLAPW) the laws of formation of electronic and atomic structure of coaly and nitrogenated iron compounds are investigated. New interpretation of appropriate Mossbauer spectra is given. · On the basis of numerical computations of the known Eilenberger equations for Green functions, the influence of impurity on quantum states and energy spectra in multilayered superconducting systems with insulator and normal metal layers is investigated. · The homogeneous generalized governor equation for the distribution function of mltipartial system is obtained taking into account initial correlations. The integrability of the Habbard model which is modified on a case of the four-fermion orbital interaction in quantum chains. The effect of spatial separation of conductivity electrons (analogue of the Hall effect) in multilayered metal structures is investigated. The harmonic Frenkel-Kontorova model is exactly solved at arbit rary temperature. The possibility of self-organized 1D nanosttructures is rigorously proven. · The lowest critical dimension in massive amorphous spin glasses is experimentally investigated. The connection between temperature phase transitions, volumetric superelastic properties and superstructure of alloys Fe-Ni-Co-Ni is analyzed.
