ABSTRACT:
A Bi-Sr-Ca-Cu-O system superconducting thin film formed on a substrate comprising [110] single crystals of an ABO.sub.3 type oxide having a perovskite structure, in which a (119) face is selectively grown relative to a substrate surface. The film is formed on the substrate by chemical vapor deposition process. A method of manufacturing a BiSrCaCuO system superconducting film in which an a-axis is oriented preferentially relative to the surface of a substrate comprising MgO (100) single crystals, wherein the chemical composition ratio (Sr+Ca+Cu)/Bi of the BiSrCaCuO system superconducting film is made not less than 3.5. A Bi-Sr-Ca-Cu-O system superconducting thin film formed on a substrate comprising MgO [110] single crystals, in which a (110) face is selectively grown to the substrate surface. The film is formed on the substrate by a chemical vapor deposition process.
