Abstract:
1. An oxide superconducting thin film, comprising a substrate, an intermediate layer provided on the substrate, and a superconducting layer provided on the intermediate layer, wherein the intermediate layer comprises an average thickness from 10 nm to 20 nm and a surface roughness Ra of 0.5 nm or less, the intermediate layer includes MgO with an NaCl-type crystal structure or CeO an average value of a valence of the Ce element in the CeO an average value of a valence of the Mg element in the MgO as weighed by abundance is from 1.85 to 1.95, and the superconducting layer is formed on a surface of the intermediate layer and includes an oxide superconductor as a main component.
