Abstract

If two anisotropic superconductors are in perfect contact, the persistent current normal to a sufficiently long interface must be accompanied by spontaneous creation of a vortex chain at the boundary (in zero external field). The phenomenon is due to peculiar boundary conditions which should be imposed upon currents at the interface. The vortices are subject to the Lorentz force along the interface, thus providing the possibility of an extra dissipation and reduction of the critical current across the grain boundary.
