Abstract

This letter describes the scaling behavior and Josephson properties of improved YBCO/PBCO/YBCO edge‐type junctions. The critical current, normal‐state resistance, and I_cRnproduct scale with barrier thickness and junction area. The coherence length of the PBCO barrier is estimated to be between 5 and 8 nm. As unambiguous evidence of the Josephson behavior, the microwave response as a function of microwave power, as well as the current modulation with applied magnetic field, have been studied: well‐developed Shapiro steps at 10 GHz have been observed, and the modulation of I_c(H) shows Fraunhofer‐like behavior with 95% I_c suppression.
