Abstract:
Boundary conditions to the Ginsburg–Landau equations are found for the problem
of the Josephson tunnel contact in the presence of small concentration of nonmagnetic
admixture in the superconductors. It is shown that in the case of small trasparency, the
change of the coefficient in the boundary condition due to the admixtures compensates
exactly the corresponding change of the coefficient in the expression of the current. As a result, the effect of the admixtures vanishes. If the transparency is not small, the
admixtures change the value of the Josephson current; in particular, in the limit of
large admixtures decreasing of the value of the current is determined by factor $l/\xi_0$.
