Abstract:
A method of manufacturing a superconductor wire which comprises the steps of:rolling a polycrystalline metallic substrate;heating the rolled polycrystalline metallic substrate at a temperature of 900.degree. C. or more in a non-oxidizing atmosphere, whereby obtaining a rolled textured structure which is orientated such that the {100} plane thereof is parallel with a rolled plane and the <001> axis thereof is parallel with a rolled direction;heating the polycrystalline metallic substrate of the rolled textured structure at a temperature of 1,000.degree. C. or more in an oxidizing atmosphere, whereby forming an oxide crystal layer consisting essentially of an oxide of the polycrystalline metal; andforming an oxide superconductor layer on the oxide crystal layer.
