Abstract
We report measurements on YBa2Cu3O7-delta (YBCO)/PrBa2Cu3O7-delta/YBCO asym metric 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 ene rgy state into account. We discuss the crystal angle dependence of d-wave J osephson current on microwave irradiation properties and the comparison bet ween several junctions with different crystal angles normal to the interfac e boundary.
