ABSTRACT:
This invention is directed to a method of preparing a superconducting metal oxide film on a substrate. More particularly, the method comprises depositing a superconducting metal oxide precursor film on the substrate and then subjecting it to annealing in an oxygen nitrogen atmosphere followed by annealing in an oxygen atmosphere, followed by rapid cooling, according to schedule wherein the time and temperature are critically defined.
