    摘要: The cross section of a wire is round and is composed of several units, each consisting of tape-like superconductors laminated in an approximately rhombic shape, which are arranged such that they form a hexagon as a whole.
    Oxide superconducting tape wires each consisting of a plurality of oxide superconducting filaments are arranged in rotational symmetry to a core. The oxide superconducting filaments have the cross section such that the average thickness is 3 to 20 µm and the average aspect ratio is larger than 2 and smaller than 10. A step of arranging the oxide superconducting tape-like wires in rotational symmetry is accomplished when the multi-core tape-like wires are packed in a third metal pipe which becomes a metal sheath later.
    Since the multi-core tape wires having oxide superconducting filaments are arranged in rotational symmetry, the oxide superconductor in the oxide superconducting filaments permits its c axis to orient in various directions. This makes it possible toss prevent the critical current from decreasing irrespective of the direction in which the magnetic field is applied and to increase the critical current density (Jc) because the oxide superconducting filament has an optimal size. The oxide superconductor should be a bismuth-based oxide superconductor, preferably be the one which has a composition of Bi 2 Sr 2 Ca 1 Cu 2 O x .

    摘要: An elongated superconducting body (68a) has a core of superconducting oxide grains (82). The grains have at least one thin first dimension that is less than or equal to ten times the average length of the superconducting oxide grains of a first significant fraction in the core. The body has a constraining non-superconducting boundary member substantially circumscribing the superconducting core (80). The superconducting body can be fabricated by providing a metallic precursor core of the metallic elements of the superconducting oxide in substantially the stoichiometric proportions to form the superconducting oxide; providing a constraining non-superconducting boundary member substantially circumscribing the metallic precursor core; deforming the combined metallic precursor core and boundary member to an elongated shape having at least one thin first dimension; and heat treating the deformed combined precursor core and boundary member so as to produce a first significant fraction of oxide superconductor grains of the precursor core having an average length that is greater than one-tenth the thin first dimension of the deformed metallic precursor core.
