Oxydsupraleitender Draht und Verfahren zu dessen Herstellung

摘要

There is proposed a superconductor wire which comprises a polycrystalline metallic substrate (1) having a rolled textured structure where the ä100ü plane thereof is parallel with a rolled plane and the &lang&001&rang& axis thereof is parallel with a rolled direction, an oxide crystal layer (2) consisting of an oxide of the polycrystalline metal which is formed on a surface of the polycrystalline metallic substrate (1), and an oxide superconductor layer (4) formed on a surface of the oxide crystal layer (2), wherein 90% or more of the ä100ü plane of the oxide crystal layer is inclined at most at an angle of not more than 10 DEG to the surface of the polycrystalline metallic substrate (1).
