Abstract

PURPOSE:To produce a superconductive layer evenly throughout the whole length and to increase the mechanical strength by diffusing Cu of a coverage layer at the outer surface of a base material, O in the ambiance gas in the heat treatment time, or Cu and O of a copper oxide membrane, and A and B elements of a mixing material layer each other, in the manufacture of an A-B-Cu-O system oxide superconductive material. CONSTITUTION:In the manufacture of an oxide superconductive material of a general formula A-B-Cu-O (where A is one or more of the periodic table group IIIa elements such as Y, Sc, La, Yb, Er, Eu, Ho, and Dy, and B is one or more of alkaline earth metal elements such as Be, Mg, Ca, Sr, and Ba), a coverage layer consisting of Cu is formed on the surface of a base material. Then, at the outer surface of the coverage layer, a copper oxide membrane is formed. After that, at the outer surface of the copper oxide membrane, a mixing material layer including A and B elements is formed to make a laminate material. And then, the first heat treatment at the temperature lower than that to produce a superconductor in an inert gas ambiance, the second heat treatment at the temperature to produce the superconductor, and the final heat treatment at the temperature to produce the superconductor in the ambiance including oxygen are applied to the laminate material.
