Non-Fraunhofer patterns of the anharmonic Josephson current influenced by a strong interfacial pair breaking

摘要

In the junctions with a strong Josephson coupling and a pronouncedinterfacial pair breaking, the magnetic interference patterns of the Josephsoncurrent are shown to differ substantially from the standard Fraunhofer shape.The Fraunhofer pattern occurs, when Josephson couplings are weak. The narrowpeak of the critical current, centered at the zero magnetic field, and thesuppressed hills at finite field values are the characteristic features of thenon-Fraunhofer magnetic field modulation of the critical current, obtained inthis paper.
