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