We report the measurement and analysis of critical current(Ic)modulation and microwave response in magnetic field for a set ofYBa2Cu3O7-YBa2Co0.15Cu2.85O7-YBa2Cu3O7ramp-edge Josephson junctions. These junctions have been fabricated with various widthswto span the transition from the moderately small(w<2&lgr;J)to the moderately large(w>2&lgr;J)junction limit at 77 K. Aswincreases, both theIcmodulation and microwave absorption behavior independently suggest a growing contribution from edge supercurrents. The addition of a superconducting ground plane was shown to reduce the edge supercurrent effects. ©1997 American Institute of Physics.
