ABSTRACT:
A superconducting Y.sub.1 Ba.sub.2 Cu.sub.4 O.sub.2 thin film is formed by a metalorganic deposition method which comprises depositing a solution comprising neodecanoates of Y, Ba and Cu and a solvent having at least approximately 5 volume percent pyridine in xylene onto a substrate selected from the group consisting of strontium titanate, barium titanate, and sapphire; pyrolyzing the coated substrate to thermally decompose the neodecanoates at a temperature of about 500.degree. C. followed by a rapid thermal annealing.
