Abstract(in English) | We have measured two-dimensional magnetic field dependence of the Josephson current through Nb/Al-AlOx/Nb Josephson junction by applying the magnetic fields (Hx, Hy) in the direction parallel to the junction plane two-dimensionally. We can obtain much information about the characteristics of the Josephson junction by measuring two-dimensional magnetic field dependence of the Josephson current. Furthermore, we have measured the modulation characteristics of the Josephson current by applying the magnetic field Hz in the direction perpendicular to the junction plane. When the perpendicular magnetic field Hz is applied to the Josephson junction, the Josephson current is irreversibly modulated due to the trapped magnetic flux in the Nb superconducting thin film. In this study, we measured two-dimensional magnetic field dependence of the Josephson current at each value of the perpendicular magnetic field Hz. We investigated the perpendicular magnetic field dependence of the Josephson current by applying the parallel magnetic fields (Hx, Hy) in addition to the perpendicular magnetic field Hz. |
