摘要：

Current transport across each of the two YBa2Cu3O7-Au interfaces in a step-edge superconductor-normal metal-superconductor (SNS) Josephson junction could be investigated independently, due to contacts to the Au interlayer. The I-V characteristics of each superconductor-normal metal (SN) interface showed de and sc Josephson-like effects fitting well to a model, which takes into account the influence of proximity effect in the normal metal layer on the transport across the SN interface, and Andreev reflection at the interface. Fn the investigated junctions, both SN interfaces of the step SNS junctions had similar transparencies. (C) 1996 American Institute of Physics.
