  • Oxide superconductor, manufacturing method therefor, and base substrate therefor
    Publication number: 20040224851
    Abstract: An oxide superconductor of the present invention characterized in that it comprises: a substrate 1 made of metals having a high melting temperature; at least one oxide intermediate layer 2 and 3 which is formed on at least one surface of the substrate 1; and a thick film oxide superconductor layer 5 which is formed on the oxide intermediate layer 2 and 3 by the liquid phase epitaxial method in which the substrate 1 provided with the oxide intermediate layer 2 and 3 is put into a solution 7 containing the elements comprising an oxide superconductor layer, and is then pulled out from the solution 7.
    Type: Application

  • Oxide superconducting electroconductive article and method for its preparation
    Publication number: 20030176287
    Abstract: The present invention provides an oxide superconducting conductor A comprising an oxide buffer layer 2 on a base material 1 composed of a high melting point metal, a solid solution layer 4 having a structure similar to an oxide superconducting substance containing constituent elements of the oxide buffer layer 2 on the oxide buffer layer 2, and an oxide superconducting layer having a peritectic temperature lower than that of the solid solution layer 4 having a structure similar to an oxide superconducting substance on the solid solution layer 4 having a structure similar to an oxide superconducting substance.
