| Popis: | We report the measurement and analysis of critical current (Ic) modulation and microwave response in magnetic field for a set of YBa2Cu3O7-YBa2Co0.15Cu2.85O7-YBa2Cu 3O7 ramp-edge Josephson junctions. These junctions have been fabricated with various widths w to span the transition from the moderately small (w 2λJ) junction limit at 77 K. As w increases, both the Ic modulation 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. |
