Bi-Sr-Ca-Cu-O system superconducting thin film and method of forming the same.

摘要

A method of forming a Bi-Sr-Ca-Cu-O system (Bi2Sr2CaCu2Ox) superconducting thin film in which two half-unit cells constitute a Perovskite structure layer, characterized in that Sr and Bi, which are present between said half-unit cells, are each deposited without oxidation by using an MBE process or MO-MBE process with an atomic layer controlling level ability. A critical current density of the Bi-Sr-Ca-Cu-O system superconducting thin film is not significantly reduced.
