摘要：
The vertical four-probe measurements for (110)-PrBa2Cu3O7-delta/YBa2Cu3O7-delta bilayers pseudomorphically grown on (110)-YBa2Cu3O7-delta (YBCO) single crystal substrates show clearly two superconducting transition steps associated with two different T-c's of 92.0 K of YBa2Cu3O7-delta and 75.5 K for 220 nm thick PrBa2Cu3O7-delta. The simultaneous PrBa2Cu3O7-delta/YBa2Cu3O7-delta bilayers on (001)-YBa2Cu3O7-delta (YBCO) single crystal substrates show a non-superconducting nonlinear I-V curve.
