Abstract
A thin film of an oxide superconductor having a homogeneous composition and less oxygen defects is produced by independently vaporizing onto a substrate at least one material selected from the group consisting of the elements of Ia, IIa and IIIa groups of the periodic table and their compounds and one material selected from the group consisting of Cu and its compounds and irradiating the substrate with oxygen ions and depositing the vaporized materials together with oxygen on the substrate to form the thin film of the oxide superconductor.
