Abstract
An epitaxial thallium-based copper oxide superconducting film is formed on a crystalline substrate by metalorganic deposition which comprises forming a film of carboxylate soap solution on said substrate, prepyrolyzing said film at a temperature of 350.degree. C. or less and pyrolyzing said film at a temperature of 800.degree.900.degree. C. in the presence of oxygen and an overpressure of thallium for a sufficient time to produce said epitaxial superconducting film.
