摘要：

All-high-T(c) Josephson junctions consisting of a YBCO / barrier / YBCO-layered structure using epitaxial YBCO films sputtered on MgO(100) have been successfully fabricated. The barrier layer was obtained by Ar + O2 plasma treatment of the surface of the base electrodes. These junctions show superconductor / normal-metal / superconductor (SNS)-like current-voltage characteristics. Constant-voltage current steps observed in response to 10 GHz microwave radiation show that ac-Josephson effects occur in these junctions.
