ABSTRACT:
A method of forming a superconducting oxide material comprises the steps of forming of a superconducting oxide material into a thin film on a film-forming surface portion, creating a plasma to form an activated oxygen atmosphere, subjecting the thin film to a magnetic field through the thickness of the thin film, thereby injecting the activated oxygen into the thin film so that crystals of the superconducting oxide material are aligned parallel or perpendicular to the film-forming surface portion.
