Abstract
We derive boundary conditions that connect the quasiclassical propagators for superconducting metals across magnetically active interfaces. These boundary conditions, combined with the quasi- classical transport theory, determine the structure of the perturbed superconductivity near such an interface, and are essential for a quantitative theory of Josephson tunneling and proximity effects between heavy-fermion superconductors and inhomogeneous structures composed of magnetic and superconducting materials. We discuss some qualitative features of Josephson tunneling between conventional and unconventional superconductors.
