摘要
YBaCuO/PrBaCuO/YBaCuO edge-type Josephson junctions were fabricated and their transport properties were studied. Josephson effect in these structure was confirmed by the observation of microwave induced Shapiro steps and periodic magnetic field dependence of the critical current. Normal electron transport in the junctions was well explained by Glazman and Matveev's theory for hopping transport via localized states. In addition, the supercurrent transport in PrBaCuO is possibly supported by the resonant tunneling via the localized states. We estimated the density of the localized states to be 10(16)cm(-3).
