Keywords:Josephson junction

We fabricated Nb/Al-AlOx/Nb Josephson junction and measured two-dimensional magnetic field dependence of the Josephson current by applying the magnetic field in the direction parallel to the plane of the junction. When parallel magnetic field Hx and Hy were applied, two Fraunhofer pattern were observed. When perpendicular magnetic field was applied, Josephson current was irreversibly modulated.
