Claims8
A superconducting structure comprising:
- a substrate;
- a thin film from about 5 to 500 nm in thickness of a superconducting rare earth-barium-copper oxide thereon said substrate, said thin film being a single thin film mixture including yttrium and samarium, said single thin film mixture of superconducting material characterized as having chemical and structural compatibility with said substrate, said superconducting structure including said single thin film mixture having stronger flux pinning under magnetic fields than a single thin film of YBCO alone.
