    摘要: The invention relates to a technique for forming a single crystalline thin film of good quality on an underlayer. Such a technique is suitably applicable to provision of an oxide high-temperature superconductor thin film usable for a superconducting wire material, a superconducting device or the like. The single crystalline thin film formed on a substratum is made of a substance different from that of the substratum. A specific atomic layer contained in common in the substratum and the thin film is shared at an interface between the substratum and the thin film. In a region as adjacent to the interface as 100 or fewer unit cells of the thin film apart from the interface, a ratio of crystalline region having grown with an orientation of ±2 degrees or less deviation angle on the basis of a crystal orientation of the substratum is 50% or more.

    摘要: Rare-earth-Ba—Cu—O superconductors having improved critical current density are described, as are methods of making same. These superconductors comprise a drop in Jc of less than a factor of about 7 at a temperature of between about 30K to about 77K, and at a magnetic field of about 1 Tesla, when the magnetic field is applied normal to the surface of the superconductor, as compared to a Jc in the presence of no magnetic field. These superconductors, when a magnetic field is applied perpendicular to the HTS surface have a peak Jc that is about 50-90%, and when a magnetic field is applied in any orientation with respect to the HTS surface have a Jc value that is at least about 50%, of the peak Jc that exists when the magnetic field is applied parallel to the surface of the superconductor.

    摘要: Disclosed is an oxide high temperature superconductor having a crystalline substrate of low dielectric constant formed thereon with a thin film of the oxide high temperature superconductor that is high in crystallographic integrity and excels in crystallographic orientation as well as a method of making such an oxide high temperature superconductor. In fabricating an oxide high temperature superconductor containing Ba as a constituent element and having such a substrate formed thereon with a thin film of the oxide high temperature superconductor, a first buffer layer composed of CeO3 is formed on a sapphire R (1, null1, 0, 2) face substrate for reducing lattice mismatch between the sapphire R (1, null1, 0, 2) face substrate and the oxide high temperature superconductor thin film, and a second buffer layer composed of such an oxide high temperature superconductor but in which Ba is substituted with Sr is formed on the first buffer layer made of CeO3 to allow the oxide high temperature superconductor thin film to be formed on the second buffer layer. Thus, if the first buffer layer for reducing the lattice mismatch between the sapphire R (1, null1, 0, 2) face substrate and the oxide high temperature superconductor thin film is liable to an interfacial reaction with Ba from the oxide high temperature superconductor thin film, the second buffer layer prevents the interfacial reaction, thereby permitting the epitaxial growth of an oxide high temperature superconductor thin film that excels on both crystallographic integrity and crystallographic orientation.

A second buffer film is disposed on the first buffer film, the second buffer film having a biaxial crystal texture. A superconductor layer can be disposed on the second buffer film. Ion-beam assisted deposition (IBAD) can be used to deposit the second buffer film.
