  • OXIDE SUPERCONDUCTING WIRE AND METHOD FOR MANUFACTURING SAME
    Publication number: 20190318849
    Abstract: An oxide superconducting wire includes a superconducting layer formed disposed on a substrate. The superconducting layer includes a structure in which artificial pin rods having different lengths dispersed on a plane parallel to a substrate surface of the substrate. A degree of dispersion in length of the artificial pin rods in the plane parallel to the substrate surface is greater than or equal to 5 mm.

  • Oxide superconducting conductor and method of manufacturing the same
    Patent number: 8772201
    Abstract: 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.
