Abstract
A superconducting structure is provided comprising a substrate, a superconductor coating supported by the substrate and a diffusion barrier positioned between the superconductor coating and the substrate to inhibit diffusion of contaminants from the substrate to the superconductor coating. The coating is a ceramic oxide having superconducting properties. The diffusion barrier may likewise be a ceramic oxide, but differs in its specific composition to provide it with a peritectic decomposition temperature greater than the superconductor coating. Accordingly, the diffusion barrier exhibits substantially lower atomic mobility than the superconductor coating during manufacture of the superconducting structure, thereby preventing contamination of the coating by the substrate.
