摘要： A superconducting wire according to one embodiment of the present disclosure includes: a substrate having a first surface and a second surface; a superconducting layer having a third surface and a fourth surface; and respective coating layers. The second surface is opposite to the first surface. The fourth surface is opposite to the third surface. The superconducting layer is disposed on the substrate such that the third surface faces the second surface. The respective coating layers are disposed on the first surface and the fourth surface. Adhesion strength between the substrate and the coating layer disposed on the first surface is lower than adhesion strength between the superconducting layer and the coating layer disposed on the fourth surface.

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： A superconducting wire includes a substrate and a superconducting material layer. The substrate includes a first main surface and a second main surface opposite to the first main surface. The superconducting material layer is disposed on the first main surface. Along at least a part of the superconducting wire in a direction in which the superconducting wire extends, the superconducting material layer is disposed to cover a side surface of the substrate in a width direction of the substrate and cover at least a part of the second main surface. A thickness of the superconducting material layer located on the first main surface varies along the width direction. A maximum thickness of the superconducting material layer located on the second main surface is smaller than a maximum thickness of the superconducting material layer located on the first main surface.

摘要： Provided is a reinforcing-member-equipped oxide superconducting wire in which occurrence of defects such as separation of a reinforcing member due to a decrease in the strength of an edge portion is sufficiently suppressed, problems such as separation of a reinforcing member do not occur even when a force in a thickness direction is applied, and stable superconducting properties can be maintained. The reinforcing-member-equipped oxide superconducting wire includes an oxide superconducting wire and two reinforcing members that are disposed so as to sandwich the oxide superconducting wire. The reinforcing members are bonded to the oxide superconducting wire using solder, and each of the reinforcing members has a width equal to or smaller than a width of the oxide superconducting wire or at least surfaces of the oxide superconducting wire, the surfaces facing the reinforcing members, are covered with copper, nickel, or an alloy containing at least one of these metals.
