Paper Abstract

We have studied the superconducting critical current 1. of Y1Ba2Cu3O7,-Ag/M-Pb proximity junctions. The current-voltage (I.V) characteristics are typically those of a superconductor-normal metal-superconductor (S-N-S) junction. The Y1Ba2Cu3O7.-Ag/Al-Pb junctions show sharp Shapiro steps in a microwave field. The dependence of step height on microwave power is well described by the Resistively Shunted Junction (RSJ) model, assuming a IC cx: Sin ( Josephson behaviour, where ço is the pha difference of the superconducting order parameter across the junction. The Josephson current shows an interference pattern in a magnetic field applied parallel to the junction plane.
