Abstract
A method for producing an oxide superconducting connecting line includes initially coating a line with at least one layer of a crystalline or amorphous metal alloy forming a superconductive oxide. The line is subsequently heated to a temperature below the melting temperature of the oxide. A gas containing oxygen is simultaneously brought into contact with the accessible surface forming an oxide film which is superconductive upon cooling. When the oxide film is damaged at a certain location, the still-undamaged layer is exposed to the oxygen-containing gas and the line is heated at the damaged location. A superconducting film is again formed. A combination superconducting connecting line and an apparatus for producing the superconducting connecting line is also disclosed.
