  • Patent number: 11264151
    Abstract: 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.

  • Publication number: 20200058419
    Abstract: Provided are a superconductive wire and a superconductive coil that have sufficient superconductivity and may be manufactured through a simple manufacturing process. The superconductive wire includes a tape-shaped substrate having a main surface and a superconductive layer provided on the main surface. A critical current flowing through an end portion in the width direction perpendicular to the extending direction of the substrate is larger than a critical current flowing through a central portion in the width direction.
