摘要：

Step edge Josephson junctions and dc SQUIDs made of laser ablated and sputtered YBCO films and grain boundary junctions in polycristalline TBCCO films have been investigated. Bridges in the micrometer scale have been structured by laser or ion beam etching as well as by the inhibit-layer technique. The Josephson junctions are characterized comparing I-V measurements under microwave irradiation to calculations within RSJ model with finite capacitance and white noise. The dependence of the ICRN product on temperature can be fitted to microscopic theory of SNINS or SNS junctions with additional temperature-independent pair breaking. Flux modulation and noise properties of the dc SQUIDs at 77 K are shown.
