Superconductive thin film material and method of manufacturing the same

Abstract

A superconductive thin film material which achieves good superconductivity by preventing an element diffusion reaction and a manufacturing method of the superconductive thin film material are provided. A superconductive thin film material is provided with a substrate, an intermediate layer with one layer or at least two layers formed on the substrate, and a superconductive layer formed on the intermediate layer. The intermediate layer has a thickness of not less than 0.4 μm. The material for forming the intermediate layer is preferably oxide having a crystal structure, which is at least one of a halite type, a fluorite type, a perovskite type, and a pyrochlore type.

Dependencies are inferred from the claim text.
