| 简介 |
An oxide superconducting conductor of the invention is configured to include an oxide superconducting layer including a substrate and an oxide superconductor formed on the substrate. The oxide superconductor being expressed by a composition formula of RE1Ba2Cu3Oy where RE represents a rare earth element and an expression of 6.5 < y < 7.1 is satisfied. A normal conduction phase including Ba and a different phase including an alkaline earth metal having an ionic radius smaller than that of Ba are dispersed in the oxide superconducting layer. The normal conduction phase is an oxide including Ba and one selected from a group consisting of Zr, Sn, Hf, Ce, and Ti. |
