Abstract

Film bicrystal Josephson junctions of a new type based on a metal oxide high-T c superconductor of the YBa2Cu3O7−x (YBCO) system are suggested and studied. In junctions of the new type, in contrast to the known ones, the working surfaces situated on the opposite sides of the bicrystal interface have different crystal orientations: one is (001)YBCO, and the other is rotated (misoriented) relative to it by an asymmetric bicrystal angle around a certain axis lying in the substrate plane. The main electrical and dynamic (microwave) characteristics have been determined for junctions of the new type based on NdGaO3 bicrystal substrates with the misorientation angle varying from 13° to 28°. These junctions exhibit high values of the critical parameters at T=77 K, including the critical current density I C= (2–5)×105 A/cm2 and the characteristic voltage V C=I C R N=0.6–0.9 mV. Advantages of the bicrystal Josephson junctions of the new type over the known junctions are considered.
