摘要： A superconducting wire includes a multilayer stack and a covering layer (stabilizing layer or protective layer). The multilayer stack includes a substrate having a main surface and a superconducting material layer formed on the main surface. The covering layer (stabilizing layer or protective layer) is disposed on at least the superconducting material layer. A front surface portion of the covering layer (stabilizing layer or protective layer) located on the superconducting material layer (front surface portion of the stabilizing layer or upper surface of the protective layer) has a concave shape.

摘要： This invention provides a substrate for a superconducting wire used for manufacturing a superconducting wire with excellent superconductivity and a method for manufacturing the same. Such substrate for a superconducting wire exhibits the crystal orientation of metals on the outermost layer, such as a c-axis orientation rate of 99% or higher, a Δω of 6 degrees or less, and a percentage of an area in which the crystal orientation is deviated by 6 degrees or more from the (001) [100] per unit area of 6% or less.

摘要： An oxide superconducting thin film wire includes a metal substrate, a laminate, and a Cu stabilizing layer. The metal substrate includes a supporting base material and a conductive layer located on the supporting base material. The conductive layer includes a Cu layer serving as an internal layer and a biaxially orientated surface layer. The laminate includes a buffer layer, an oxide superconducting layer, and a Ag stabilizing layer stacked on the metal substrate in this order from the metal substrate. The Cu stabilizing layer is formed so as to surround the laminate and the metal substrate. At least one of the Cu stabilizing layer and the Ag stabilizing layer is formed so as to be in contact with at least a portion of the conductive layer of the metal substrate and be electrically conductive with the conductive layer of the metal substrate.

摘要： An oxide superconducting wire includes an oriented metal substrate, an intermediate layer formed on the oriented metal substrate, and an oxide superconducting layer formed on the intermediate layer. The oriented metal substrate has an in-plane orientation Δϕ of 7° or less. The intermediate layer is formed of a single layer.
