A method of manufacturing a high temperature superconductor current coated tape

A superconducting article is disclosed, including a substrate and a chemical vapor deposited thin film superconducting layer overlying the substrate, the superconducting layer having a critical current not less than about 100 A/cm width at 77K and self field. The superconducting article may be a tape, multiple tapes, or a power device, such as a power cable, power generator, or power transformer. Also disclosed are methods for manufacturing same and methods for using same.
