Abstract

Fabrication and characterization of YBa₂Cu₃O _y Josephson junctions with step-edge, bi-epitaxial, and sandwich geometries are performed in this study to investigate the effects of microwave irradiation on the I-V characteristics. I-V curves under microwave irradiation reveal Shapiro steps. The width of the constant voltage steps were modulated by the microwave power. The period of the magnetic induction ΔB detected from the V-φ curves for superconducting quantum interference devices is temperature dependent. Additionally, T_c and I_c of the proximity sandwich junctions are enhanced by the microwave irradiation.
