In-situ fabrication of SNS junction consisting of YBaCuO/PrBaCuO/YBaCuO structure

All high-T/sub C/ superconductor-normal conductor-superconductor (SNS) junctions have been fabricated using in-situ deposition of YBaCuO/PrBaCuO/YBaCuO trilayer films. The trilayer films of YBaCuO(200 nm)/PrBaCuO(50 nm)/YBaCuO(100 nm) with c-axis orientation were fabricated on the
