Abstract
PURPOSE:To make it possible to increase critical electric current density by laminating at least one side of a superconductive layer to two or more layers by reciprocally laminating a sputtering superconductive layer belonging to a system formed by a sputtering method and a MBE superconductive layer belonging to a system formed by a molecular beam epitaxy method. CONSTITUTION:An oxide superconductor 1 is composed of three layers: a first superconductive layer 1a formed by a sputtering method on a substrate 2, a second superconductive layer 1b formed by a MBE method on the layer 1a, and a third superconductive layer 1c formed by a sputtering method on the layer 1b. The surface temperature of the substrate 2 in sputtering is made to a 700-1000 deg.C degree, and a sputtering atmosphere is made to an atmosphere, for instance, composed of inert gas such as argon gas. A conductor belonging to an A-B-C-D system is used as an oxygen superconductor, for instance, in the case of an oxide superconductor belonging to a Y-Ba-Cu-O system, the following formula Y:Ba:Cu:O=1:2:3:(7-delta) is applied, and delta is made to have the range of 0<=delta<=5.
