Abstract

Investigation of sandwich-type Josephson junctions using a Bi2Sr2CaCu2Ox/Bi2Sr2CuOy/Bi2Sr2CaCu2Oz (BSCCO/BSCO/BSCCO) structure. The barrier layer (BSCO) has crystalline structure similar to that of superconducting electrodes (BSCCO). Moreover, the BSCO film was conductive even at 4.2 K. The junctions exhibited S/N/S type I-V characteristics. The clear Shapiro steps appeared
