Superconducting Thin Film Material, Superconducting Wire, and Method of Manufacturing the Same

摘要

A superconducting thin film material is provided, including a first superconducting thin film having a surface subjected to smoothing and a second superconducting thin film formed on the surface of the first superconducting thin film subjected to the smoothing. Further, a superconducting wire is provided, including a substrate, an intermediate layer formed on the substrate, and a superconducting layer formed on the intermediate layer, wherein the superconducting layer is made of the superconducting thin film material described above. Furthermore, a method of manufacturing the superconducting thin film material and a method of manufacturing the superconducting wire are provided.
