  • Strong high-temperature superconductor trapped field magnets
    Patent number: 6025769
    Abstract: A trapped field magnet formed of a high temperature type II superconductor material is disclosed. The trapped field magnet is formed of a plurality of relatively small, single-grain superconductive elements. Optimal shaped of these elements is in a regular truncated cone wherein the half cone angle is 55.degree., and the optimal orientation of each single-grain superconducting elements is an angle of .phi..sub.m with respect to the axis perpendicular to the upper and lower surface of the element, wherein the .phi..sub.m =3 sin .theta. cos .theta./(3 cos.sup.2 .theta.-1) and .theta. determines the location of the element.
    Type: Grant
    Filed: October 7, 1996

    Assignee: University of Houston
    Inventors: Ching-wu Chu, Yuyi Xue, Li Gao, Ruling Meng, Diego Alberto Ramirez
  • Method for synthesis of high-temperature Hg-Ba-Ca-Cu-O (HBCCO) superconductors
    Patent number: 5578551
    Abstract: The present invention is a controlled vapor/solid reaction process for the synthesis of samples of bulk compositions with a structure defined by the homologous series HgBa.sub.2 Ca.sub.n-1 Cu.sub.n O.sub.2n+2+.delta. [Hg-12(n-1)n] with n=2, 3, . . . with up to 75 to 90% Hg-1212 and 65 to 75% Hg-1223 by volume, which display sharp superconducting transitions up to 135 K.
