Abstract

A superconducting film is disclosed which has the following composition: EQU (Nd, Ba).sub.3 Cu.sub.3 O.sub.7-d where d is a number greater than 0 but smaller than 0.5. The superconducting film has the same crystal structure as that of YBa.sub.2 Cu.sub.3 O.sub.7 except that part of the Nd sites and/or part of the Ba sites are occupied by Ba and Nd atoms, respectively.
