摘要

We report measurements on YBa2Cu3O7-delta (YBCO)/PrBa2Cu3O7-delta/YBCO asymmetric ramp-edge Josephson junctions whose ab-plane orientation relatively rotated by 45 degrees. The temperature dependence of the maximum Josephson current I-c is in good agreement with the d-wave theory taking the zero energy state into account. We discuss the crystal angle dependence of d-wave Josephson current on microwave irradiation properties and the comparison between several junctions with different crystal angles normal to the interface boundary.
