Abstract:
1. A process for producing a rare earth oxide superconductor, comprising: mixing cerium with 5 to 90 mol %, in terms of the metal content, of at least one rare earth element Re selected from the group consisting of Y, Nd, Sm, Gd, Eu, Yb, Ho, Tm, Dy, La and Er; applying the mixture onto a surface of a metal substrate by liquid phase, metal organic deposition; calcining the applied mixture at a temperature of 900° C. or higher and lower than 1200° C. under a reduced pressure of 0.1 Pa or higher and lower than atmospheric pressure to form an intermediate layer comprising a cerium oxide; and then forming a rare earth oxide superconducting layer on the intermediate layer.
