    Abstract

    Using thin-film ramp-type Josephson contacts between a high-Tc and a low-Tc superconductor, experiments to study the dx2-y2-wave-induced π-phase-shift effects in planar Josephson arrays have been enabled. The presented studies include the first experimental realization of various complex Josephson arrays with built-in π-phase shifts, investigations on the order parameter symmetry in various high-Tc cuprate superconductors, the first direct imaging of dx2-y2-wave induced Josephson current counter flow, and half-integer magnetic-flux quantum effects in one- and two-dimensional arrays.
