    摘要: The present invention relates to a rare earth element oxide superconductive wire material improved in orientation by forming the bed layer by the MOD method. In the superconductive wire material (10) produced by forming a MOD-CZO layer (2), an IBS-GZO (3), an IBAD-MgO layer (4), a LMO layer (5), a PLD-CeO2 layer (6) and a PLD-GdBCO superconductive layer (8) in this order on an electropolished substrate (1) in an oxygen atmosphere, the CeO2 layer has a value of Δφ=4.2 degrees, which is almost the same as in the case of using a mechanically polished substrate, and the GdBCO super conductive layer has a value of Ic=243 A (Jc=up to 5 MA/cm2), which is almost the same as in the case of using a mechanically polished substrate.

    摘要: An RE123-based superconducting wire includes a base material, an intermediate layer formed on the base material, and an oxide superconducting layer which is formed on the intermediate layer and includes an oxide superconductor having a composition formula represented by RE1Ba2Cu3O7−δ (RE represents one or two or more rare earth elements), in which the oxide superconducting layer includes 0.5 to 10 mol % of a Hf-including compound dispersed in the oxide superconducting layer as an artificial pinning center, a film thickness d of the oxide superconducting layer is d>1 μm, and a current characteristic of Jcd/Jc1≧0.9 (Jc1 represents a critical current density when the thickness of the oxide superconducting layer is 1 μm, and Jcd represents the critical current density when the thickness of the oxide superconducting layer is d μm) is satisfied.
