Abstract

In the formalism of the equations of the diffusive limit of the microscopical theory of the superconductivity (Usadel equations formalism), we explain the experimental results on the spin-valve effect investigations in Nb/Ho epitaxial structures. The theory of the quasi-normal metal effect on the superconductor/strong ferromagnet critical characteristics has given. The effect of the generation of the superconducting condensate short-range triplet component on the critical temperature has explained by the condensate state functions calculations.
