A superconductive structure including a dielectric oxide substrate, a thin buffer layer of a superconducting material thereon; and, a layer of a rare earth-barium-copper oxide superconducting film thereon the thin layer of yttrium-barium-copper oxide, the rare earth selected from the group consisting of samarium, gadolinium, ytterbium, erbium, neodymium, dysprosium, holmium, lutetium, a combination of more than one element from the rare earth group and a combination of one or more elements from the rare earth group with yttrium, the buffer layer of superconducting material characterized as having chemical and structural compatibility with the dielectric oxide substrate and the rare earth-barium-copper oxide superconducting film is provided.
A superconducting structure comprising:
A method of improving the superconducting properties of a superconducting (rare-earth)-barium-copper oxide structure by depositing a thin buffer layer of a superconducting material characterized as having chemical and structural compatibility with the superconducting (rare-earth)-barium-copper oxide directly onto a dielectric oxide substrate and depositing a layer of superconducting (rare-earth)-barium-copper oxide directly onto said thin buffer layer, whereby measured superconducting properties of critical current and transition temperature for said superconducting (rare-earth)-barium-copper oxide structure are characterized as greater in value for the structure including said buffer layer than for a structure of said superconducting (rare-earth)-barium-copper oxide without said buffer layer.
