ABSTRACT:
A method for the passivation of superconductive rare earth cuprates involves depositing thereon a thin film of an amorphous or diamond-like carbon film of a thickness ranging from 100 .ANG. to 10 microns. The cuprate film may be in the as-deposited form, so necessitating a subsequent annealing step to convert the film to a superconducting phase and to remove the carbon.
