Abstract: PROBLEM TO BE SOLVED: To provide an oxide superconductor pseudo permanent magnet of large dimensions, capable of exhibiting superior magnetic characteristics over a wide range of magnetic field region and can be commercially stably manufactured. SOLUTION: An R-Ba-Cu-O oxide high-temperature superconductor pseudo permanent magnet is made into annular form which has a face of superconductor crystal (ab) in its axial and circumferential directions and a c-axis directed in the radial direction. The magnet can be manufactured by applying a paste of oxide high-temperature superconductor forming source material onto an annular base surface and forming an annular superconductor crystal layer by a melt growth method through the use of a seed crystal, or by forming a superconductor crystalline layer on a strip-shaped base surface in a similar method, bending it into an annulus and diffusion-jointing both ends of the ring.

Abstract: PROBLEM TO BE SOLVED: To provide a superconducting magnet power lead, which is capable of restraining heat from penetrating into a liquid helium system that contains a superconducting coil and feeding sufficient electric power to the superconducting coil. SOLUTION: A superconducting magnet power lead for feeding a current to 'a superconducting coil cooled down to liquid helium temperature of' via 'a radiation heat shielding unit, cooled down to liquid nitrogen temperature' in a superconducting magnet device is made to have a structure in which at least a part of the power lead located inside the radiation heat shielding unit is partially formed of an oxide high-temperature superconducting bulk body, whose critical temperature is higher than liquid nitrogen temperature. In this case, it is preferable that the bulk body be subjected to vacuum resin impregnating treatment to be improved in mechanical strength. When a braided lead is made to serve at least as a part of the magnet power lead except for the bulk body, stresses caused by the relative displacement of a device member is restrained from having adverse effects on the bulk body, so that the superconducting magnet power lead can be protected against damages.

Abstract: PROBLEM TO BE SOLVED: To stably supply an RE-Ba-Cu-O bulky superconductor capable of attaining high electromagnetic force at a relatively high temp. SOLUTION: An RE-Ba-Cu-O bulky superconductor (RE is La, Nd, Sm, Eu, Gd, Y, Ho or Dy) is irradiated with neutrons to disperse and incorporate 5-50% 'amorphous phase' having 10-500 nm particle diameter or 5-50% 'recrystallized phase different from parent phase in crystal orientation' in the parent phase of the superconductor. A more favorable result is obtained when the bulky superconductor in which an RE1+xBa2-xCu3O2 crystal phase different from the parent phase in the concn. of oxygen is dispersed in the parent phase, is irradiated with neutrons. The parent phase may contain the dispersed phase of RE2 BaCuO5 crystals or RE4+2dBa2+2dCu2-dOg crystals (0.2

Abstract: PROBLEM TO BE SOLVED: To obtain a method for easily magnetizing a 'superconducting magnet assembly', composed of bulk superconducting magnets having magnetic poles alternated, so that a magnetic field gradient is generated, easily at low cost. SOLUTION: After adjacent bulk superconducting magnet materials are put one over the other by a hinge, etc., as shown in Fig. 1 and connected to that they are freely open, the respective bulk superconducting magnet materials are all put one over another and magnetized in this state, and the bulk superconducting magnetic materials stack bodies having been magnetized are alternately opened and extended in parallel. In this case, the bulk superconducting magnet materials are magnetized, so that their stacked surfaces do not make contact with each other but are half-opened at an angle, so that it is easier to open the magnets after they have been magnetized.
