ABSTRACT:
A method for forming a superconducting oxide material including introducing oxygen or an oxidizing gas and a reactive gas or reactive minute particles into a plasma generating chamber; applying a magnetic field to the plasma generating chamber; supplying microwaves to the plasma generating chamber where the direction of the magnetic field and the propagation direction of the microwave are parallel such that the oxygen or the oxidizing gas and the reactive gas or reactive minute particles are converting into plasma; and the formation of a superconducting oxide material on a film forming surface positioned in the plasma generating chamber during application of the magnetic field.
