摘要
We have fabricated YBa2Cu3O7-x (YBCO)/Au/Ag/PbIn edge junctions using in-plane aligned a-axis oriented films in order to study the anisotropic coupling between YBCO and PbIn. Seven junctions were made in different directions spanning the b-c plane of YBCO on each chip. Current-voltage characteristics show a systematic change as a function of the angle of the junction direction relative to the YBCO crystal axes. We analyze the results using a superconductor-insulator-normal-metal interface model with anisotropic YBCO/Au interface resistance and discuss implications for measuring the out-of-CuO2 plane order parameter of YBCO.
