Abstract

An investigation of the surface influence on superconducting parameters (critical temperature and upper critical magnetic field) of the metallic superlattices is made. The dependence of the critical temperature on superlattice parameters (distance L between the layers with better superconducting properties and distance D between the former from these layers and surface) is obtained. The temperature dependence of the upper critical field parallel and perpendicular to the superlattice surface is found for different ratio between L and D. The dependence of the critical parameters on number n of the layers of the superlattice is calculated. It is shown that the surface of the metallic superlattice induced superconducting state contrary to that of homogeneous superconductors.
