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 atinterface.The phase dependence of the Josephson current I（φ）between s-wave and p;-wave superconductor is predictedto be sin（2φ）.The ferromagnet scattering effect,the barrier strength,and the roughness strength at interface suppressthe dc currents in s/FI/p junction.
