Dc Josephson effect in s-wave superconductor ferromagnet insulator p-wave superconductor junctions

The Josephson currents in s-wave superconductor/ferromagnet insulator/p-wave superconductor(s/FI/p) junctions are calculated as a function of temperature and the phase taking into account the roughness scattering effect at interface. The phase dependence of the Josephson current I(phi) between s-wave and p(x)-wave superconductor is predicted to be sin(2 phi). The ferromagnet scattering effect, the barrier strength, and the roughness strength at interface suppress the dc currents in s/FI/p junction.
