摘要：

The low frequency current-voltage characteristics of YBa2Cu3O7-SrRuO3-YBa2CU3O7 Josephson junctions show an increasing resistance and phase shift in fields of 0 to 8 T. A critical current is also evident up to 8 T. Data are analyzed in terms of field-induced perturbations of the current paths through the junction. Results indicate a highly inhomogeneous interface where the mean width of spatial variations in both normal and supercurrent is of order 50 to 100 Angstrom. (C) 1995 American Institute of Physics.
