Karazin popup.description2 Objects of the study: Single crystals of Y1Ba2Cu3O7- , Nb1-xSe2Snx; the bulk amorphous alloy Zr41.2Be22.5Ti13.8Cu12.5Ni10; the pure hafnium; the internal Josephson contacts. Purpose of the study: The determination of the influence of external factor on physical characteristic of material; the study of the synchronizing conditions of Josephson contact. Method of the study: The study of the electrical resistivity, in particular, under high pressure; heat conductivity, heat linear expansion; mathematical modeling. For Y1-zPrzBa2Cu3O7- it is found the conditions of the reinforcement of localizations and suppressions of super conductivity state. The electric resistance anisotropy is described by the "1/2 law". The high pressure induced redistribution of the labile oxygen in YBa2Cu3O7- with the oxygen deficit lead to the reinforcement of the phase stratification. Herewith the displacement of temperature metal-dielectric transitions areas occurs. The change in the density of states at the Fermi level contributes the main contribution to increase of Тс under pressure for single crystals Nb1-xSe2Snx. The influence of the magnetic field on the paraconductivity of YBa2Cu3O7- is interpreted within the framework of Aslamazov-Larkin model fluctuation conductivities. The residual resistivity and Lorentz number increas in pure hafnium because of nonelastic scattering of electrons on admixture. The estimation of the surface diffusion coefficient of deuterium is made for bulk amorphous alloy Zr41.2Be22.5Ti13.8Cu12.5Ni10; the heat linear expansion of this alloy in interval 77-350 К is appreciable less, than one for its polycrystalline analogue. For system internal Josephson contacts is made the model of the resonance frequencies dependencies from the system typical size with taking into account the influences of self heating on synchronizing of these contacts. The recommendations are offered on the use the result when making new samples of electronic and telecommunication equipment. The Key words: Single crystals of Y1Ba2Cu3O7- , Nb1-xSe2Snx, oxygen deficit, electric resistance anisotropy, bulk amorphous alloy, hydrogen, temperature, hydrostatic pressure, Josephson contacts.
