A superconducting device has an oxide superconducting material with a passivation or blocking film formed on its surface. The film helps to maintain a uniform oxygen concentration of the superconducting material through its thickness. The superconducting material is thus superconductive throughout its cross-section, and particularly in the vicinity of the surface bearing the film.
