Metalorganic deposition of superconducting Eu-Ba-CuO thin films by rapid thermal annealing

This patent describes a method for producing films of superconductor materials. It comprises: forming a solution from the neodecanoates of europium, barium, and copper metals, the metals form an oxide mixture exhibiting superconductive properties, the solution comprises a solvent having at least approximately 10 volume percent pyridine in xylene; depositing a film of the solution onto a substrate, the substrate selected from the group consisting of strontium titanate, barium titanate, and sapphire; pyrolyzing the film in an oxygen-containing environment at a first temperature of approximately 500 degrees C. for up to approximately 5 minutes and heating the oxide film at a second temperature ranging between about 850 degrees C. and 1000 degrees C. for a duration of up to approximately 2 minutes
