摘要： An oxide superconductive wire is provided by, for example, forming an oxide superconductive layer on a tape-type flexible base. A preliminary compressive strain is applied to the oxide superconductive layer in the longitudinal direction. The remaining strain can be provided by using a base having thermal expansion coefficient larger than that of the oxide superconductive layer and by cooling the same after heat treatment, due to contraction of the base. Since the preliminary compressive strain is applied to the oxide superconductive layer, degradation of superconductivity of the oxide superconductive layer can be suppressed even if the oxide superconductive wire is bent in any direction, compared with the wire without such strain. Therefore, the oxide superconductive wire can be coiled, for example, without much degrading the superconductivity.

摘要： When an oxide superconducting thin film is formed on a substrate by a vapor phase method such as laser ablation, for example, a plurality of grooves are formed on the substrate by photolithography or beam application in the same direction with an average groove-to-groove pitch of not more than 10 .mu.m, so that the oxide superconducting thin film is formed on a surface provided with such a plurality of grooves. Thus promoted is growth of crystals of the oxide superconducting thin film in parallel with the grooves, whereby respective directions of a-axes and c-axes are regulated to some extent. This improves critical current density of the oxide superconducting thin film.
