Abstract
A method of forming a Bi-Sr-Ca-Cu-O system (Bi.sub.2 Sr.sub.2 CaCu.sub.2 O.sub.x) superconducting thin film in which two half-unit cells constitute a Perovskite structure layer, characterized in that Sr and Bi layers, which are present between said half-unit cells, are each deposited without oxidation by using an MBE process or an MO-MBE process with an atomic layer level control capability. A critical current density of the Bi-Sr-Ca-Cu-O system superconducting thin film is not significantly reduced.
