摘要：

Multilayer Josephson edge type junctions were prepared on the edges of c-axis oriented YBa2Cu3O7 thin films structured by chemical etching in a Br-ethanol solution. Resistive PrBa2Cu3-xGaxO7 (x=0, 0.15, and 0.3) films were deposited by the high oxygen pressure de-sputtering technique and used for barrier and insulation layers. Basic properties of the junctions Such as I-c(T), I-c(d), R(n)(T), and basic: characteristics of the proximity effect such as xi(n), gamma and gamma(B) were obtained and discussed.
