When the normal material is sufficiently thin and the applied magnetic field is below the critical field of vortex nucleation, we prove to leading order that jump boundary conditions of the type predicted by de Gennes are satisfied across the junction.27 pagesAnalysis of PDEsMathematical Physics35J60 (Primary); 35J20, 35J25, 35B40, 35Q55, 82D55 (Secondary)text
