Superconducting article.

摘要

A superconducting article comprising: a substrate made of nickel or a nickel alloy; and a film of a composite oxide superconducting material containing a CuxOy-radical, formed on the surface of the substrate. In the above-mentioned superconducting article, cracks are hardly produced in the film of the composite oxide superconducting material, and oxygen in the composite oxide superconducting material is hardly absorbed into the substrate.
