摘要：

We have fabricated all-high-T(c) Josephson junctions in a planar S-N-S geometry, by bridging narrow gaps (almost-equal-to 0.1-0.2-mu-m) in epitaxial YBa2Cu3O7 (YBCO) films with Au. The resulting devices exhibit a variety of non-hysteretic I-V characteristics, with I(c)RN of order 0.1 to 10 mV, and exhibit Shapiro steps under microwave irradiation, and weak periodic modulation of the critical current with applied magnetic field. The transport properties of the junctions appear to be dominated by the Au/YBCO interfaces rather than by the Au itself.
