  • Patent number: 8512799
    Abstract: There is established a superconducting magnet made of a high-temperature bulk superconductor and capable of trapping a high magnetic field with ease and stably. The superconducting magnet made of the high-temperature bulk superconductor, for use by trapping a magnetic field, is made of the bulk superconductor with an artificial hole therein, a low-melting metal impregnated into, and filling up at least the artificial hole, and a heat-conducting metal material embedded in portions of the high-temperature bulk superconductor, impregnated with, and filled with the low-melting metal. The superconducting magnet can be produced by a process involving the steps of providing the artificial hole in the high-temperature bulk superconductor, disposing the heat-conducting metal material in at least the artificial hole, applying a process of impregnating and filling up at least the artificial hole with the low-melting metal, and subsequently, executing a process of magnetizing.
