Abstract

PURPOSE:To increase current density of a thin film higher than that of a single layered thin film by making the thin film of a superlattice structure in which superconductive layer and normal conductive layer are laminated by turns, thereby increasing interfaces. CONSTITUTION:A composite conductor of a superconductor family having a so-called superlattice structure is constituted with superconductor and normal conductor laminated by turns. Namely, Ag is deposited on a Cu substrate 1 to form a silver layer 2 on which is coated YBa2CuO7-delta 3 by sputtering process or by electron-beam deposition process. After repeating the above procedures, the material is heat treated in an atmosphere of one atmospheric pressure oxygen and formed. This increases a current density higher than that of a thin film made of a single layer of the same thickness.
