Filed: 1991-05-07
Abstract: PURPOSE:To realize satisfactory chracteristics with good reproducibility by constituting the superconductive current path and weak coupling of the title element from an oxide superconductive thin film epitaxially grown on an inclined substrate having a film-forming surface having an offset angle. CONSTITUTION:Josephson element is composed of a substrate 1 and an oxide superconductor thin film 2 formed on the substrate 1. The substrate 1 is cut as a formed film in the manner of inclining by several degrees in the direction of from (100) surface >> 110 and steps are formed on the surface along the crystal lattice of the substrate. On the other hand, the oxide superconductive thin film 2 formed on this substrate 1 is formed in the manner of accumulating on the substrate from above. In this case, however, the continuity of crystals deteriorates in the stepped part formed on the surface of the substrate 1. Therefore, when the oxide superconductive thin film 2 is thin, weak coupling is naturally formed on the stepped part. Also, this weak coupling is formed in the manner of aligning along the direction of arrangement of substrate crystals. Thus, desired characteristics can be realized with good reproducibility.
