The aim of research was to obtain new knowledge about their transport properties, to find new physical effects. A number of priority results have been obtained, among which following can be distinguished: It is proved that as the number of praseodymium magnetic atoms increases, nonmagnetic YBCO becomes a magnetic superconductor. From analysis of fluctuation conductivity, existence of fluctuation Cooper pairs in iron-selenium compound to temperatures more than twice the critical temperature was proved for the first time. It was shown for the first time that difference in anisotropy values of magnetoresistance of pressed chromium dioxide powders is related to difference in magnetic susceptibility of particles along the axis of light magnetization and in perpendicular direction. For the first time in a hole heterostructure based on germanium, very high mobility free charge carriers was detected, and value of the effective mass of charge carriers, which is very small, was determined. It was found that modification of the carbon nanotubes surface by particles of iron oxides improves their conductive properties, which is also observed in nitriding of nanotubes, which is a desirable effect for applications. Direct electrical studies of Hall spin effect in normal metals of aluminum and tungsten due to spin-orbit interaction were performed for the first time. The nonequilibrium Hall spin effect was visualized for the first time in asymmetric platinum samples in helium temperature range. The influence of magnetic breakdown on kinetic coefficients of layered organic conductors with a multileaf Fermi surface in the conditions of Lifshitz phase topological transition is determined. The Lifshitz topological transitions controlled by a parallel magnetic field in 2D electron gas with a combined spin - orbital Rashba - Dresselhaus interaction have been studied.
