    摘要: Superconductors using oxide superconducting materials having pinning centers inside crystal grains are enhanced in transmissible critical current density and allowed to have a high critical current density even in the magnetic field. A superconductor is produced comprising superconducting materials having a high irreversible magnetic field where the c axes of their crystals are oriented in one direction. This can be practically realized by heat-treating a superconducting material having the composition (Tl.sub.1-X1-X2 Pb.sub.X1 Bi.sub.X2)(Sr.sub.1-X3 Ba.sub.X3).sub.2 Ca.sub.2 Cu.sub.3 O.sub.9+X4 together with Bi.sub.2 Sr.sub.2 CaCu.sub.2 O.sub.8 having a tendency of growing in the form of plate crystal. Various apparatuses capable of working under cooling with liquid nitrogen let alone with liquid helium and having a high superconducting critical current density even in a high magnetic field can be produced.

    摘要: Superconducting magnet system using a liquid helium for its operation and a permanent current switch and a system thereof applied to the superconducting magnet system employing a permanent current loop created by a superconducting material developing superconductivity when cooled. The system includes a superconducting magnet dipped in the liquid helium, the permanent current switch for driving or interrupting the superconducting magnet, and a cryostat for accommodating the superconducting magnet and the permanent current switch, and the permanent current switch is arranged over a liquid surface of the liquid helium.
