ABSTRACT:
A process for forming a single crystal superconducting LnA.sub.2 Cu.sub.3 O.sub.7-x film, wherein Ln is at least one rare earth element and A is at least one alkaline earth element, is disclosed, which comprises simultaneously evaporating Ln, A and Cu in an atomic ratio of about 1:2:3 from discrete evaporation sources of Ln, A and Cu onto a heated substrate in a vacuum vessel while blowing an oxygen gas onto the substrate to form an oxygen-containing atmosphere, thereby forming the single crystal superconducting film on the substrate.
