  • Oxide superconductor thin film and superconducting fault current limiter
    Patent number: 9159898
    Abstract: An oxide superconducting thin film includes a substrate, and an intermediate layer and a superconducting layer provided in this order on the substrate. The intermediate layer has an average thickness of from 10 nm to 20 nm and a surface roughness Ra of 0.5 nm or less. The superconducting layer is formed on a surface of the intermediate layer and includes an oxide superconductor as a main component. A superconducting fault current limiter including the oxide superconducting thin film is also provided.
    Type: Grant

  • Oxide superconductor thin film, superconducting fault current limiter, and method for manufacturing oxide superconductor thin film
    Patent number: 9105794
    Abstract: An oxide superconducting thin film includes a substrate having a single crystal structure, the main face of the substrate and a crystal face of the single crystal structure having an angle therebetween; an intermediate layer formed on the main face of the substrate and having an axis oriented in a direction perpendicular to the crystal face; and a superconducting layer formed on the intermediate layer and containing, as a main component, an oxide superconductor having a c-axis oriented in a direction perpendicular to the surface of the intermediate layer. A superconducting fault current limiter and a method of manufacturing an oxide superconducting thin film are also provided.
