ABSTRACT:
A thick film superconductor includes a substrate and a superconducting thick film formed on the substrate. The thick film is 1-20 microns thick with an average twin spacing to film thickness ratio of about 0.016, and is formed from an aqueous solution of YBC ions doped with a particulate rare earth oxide having a diameter of about 50-500 nm. The coated substrate is heat treated, preferably above 650 degrees C. and cooled at a rate less than 15 degrees C. per hour, resulting in a substantially fully oxygenated YBCO layer.
