Oxygen plasma treatment of yttrium barium copper oxide

A method is described for the preparation of superconducting compositions in the yttrium-barium-copper oxide system. The oxygen stoichiometry required to assure the superconducting state is attained by a either a thermal annealing process or by means of plasma oxidation.
