Abstract

The authors report about the laser method of manufacturing Josephson bridge junctions on the surface of bulk YBa₂Cu₃O_7-δ ceramic. The characteristics of the junction are given. The nonmonotonical dependence of differential resistance on the value current through the junction, which was experimentally observed, is determined by the energy gap for Cupper pairs. This technology permits us to fabricate Josephson interferometers and devices containing them.
