Research purpose: to study the influence of the Josephson media on current transport and magnetic properties of granular superconductors of the 2nd kind. Research methods. methodological and theoretical basis was electrodynamics of superconductors, to describe the field of magnetic vortex in the grain and insidegrain magnetic and transport properties the layered model with the modified anisotropic London equation with the sources for the vortex and its mirror image has been used, in studying the influence of the intrinsic magnetic field on the intergranular critical current density was used isotropic London equation (grain of cylindrical geometry) and the Maxwell equation (intergranular transition), to study the influence of magnetostriction on the transport behavior the phenomenological model of the magnetostriction induced by pinning the magnetic flux has been used. Theoretical and practical results:in the London approximation the quantitative theory of the influence of the intrinsic magnetic field on the intergranular critical current with different grain sizes has been developed, a relation between the current and the degree of dispersion of the sample has been established in a sufficiently large external fields, it was found that the magnetostriction of grain leads to a reduction of critical current material. Novelty: the above results were obtained for the first time. The practical significance of the results lies in the fact that they clarify the broad range of issues in the physics of superconductivity, provide new effects in their electromagnetic behavior, including those that have an obvious potential application. Аrea of ??application: the physics of superconductivity.
