[0051] Construction of Superconducting Wires

[0052] figure 1 is a schematic cross-sectional view showing the configuration of the superconducting wire in the first embodiment. figure 1 A section in a direction transverse to the direction in which superconducting wire 10 extends in the first embodiment is shown. Therefore, the direction transverse to the plane of the drawing is the longitudinal direction of the superconducting wire, and the superconducting current in the layer 5 of superconducting material flows in the direction transverse to the plane of the drawing. In addition, in figure 1 And in the schematic cross-sectional views in subsequent figures, in order to facilitate easy recognition of the drawings, the distance between the dimension in the vertical direction (hereinafter also referred to as "thickness direction") and the dimension in the left-right direction (hereinafter also referred to as "width direction") is shown. The difference is small. However, in r...

Abstract

A superconducting wire rod (10) is provided with a substrate (1) and a superconducting material layer (5). The substrate (1) includes a first main surface (1a), and a second main surface (1b) on the reverse side of the first main surface (1a). The superconducting material layer (5) is disposed on the first main surface (1a). At least in a superconducting wire rod part in the direction in which thesuperconducting wire rod (10) extends, the superconducting material layer (5) is provided such that the side surfaces of the substrate (1) in the width direction of the substrate (1) and at least a part of the second main surface (1b) are covered with the superconducting material layer. The thickness of the superconducting material layer (5) positioned on the first main surface (1a) changes in the width direction. The maximum thickness of the superconducting material layer (5) positioned on the second main surface (1b) is smaller than the maximum thickness of the superconducting material layer (5) positioned on the first main surface (1a).

Description

technical field [0001] The present invention relates to a superconducting wire, and more particularly to a superconducting wire in which a superconducting material layer is formed on a substrate. Background technique [0002] In recent years, superconducting wires in which a superconducting material layer is formed on a metal substrate are being developed. In particular, oxide superconducting wires have attracted attention. The oxide superconducting wire includes a layer of a superconducting material made of an oxide superconductor, which is a high-temperature superconductor having a transition temperature equal to or higher than the temperature of liquid nitrogen. [0003] Such an oxide superconducting wire is generally manufactured by forming an intermediate layer on an orientation-aligned metal substrate, forming an oxide superconducting material layer on the intermediate layer, and further forming a stabilizing layer of silver (Ag) or copper (Cu) (See, for example, Jap...
