Definitions

  • an oxide system superconductive material may be a material selected from, for instance, Y-Ba-Cu-0, Bi-Sr-Cu-O, Bi-Pb-Sr-Ca-Cu-O, TI-Ba-Cu-O, TI-Ba-Ca-Cu-O, TI-Sr-Ca-Cu-O, La-Sr-Cu-O, La-Ba-Cu-O, and a material having a lower thermal conductivity at a lower temperature than a room temperature (equivalent to having a larger electric resistance) may be a material selected from, for example, an alloy including Au or Ag as a main component and at least one element of Pd, Pt, Mn, Mg, Zr, and Au, a material including a transition metal system alloy as a main component which will be oxide at a thermal treatment of a superconductive material, and an oxide system material such as alumina, MgO, LaAtO s .
  • the core 8 is of an oxide system superconductive material(TI-Pb-Sr-Ba-Ca-Cu-O) including 1223 phase of TI and Pb single layer system as a main component
  • the alloy covering layer 9 is of Au-5 atomic % Pb alloy, wherein each superconducting tape is 2.4 mm in width, 1.4 mm in thickness, and 3.3 mm 2 in cross-sectional area.
  • the superconductive current lead 4 thus fabricated is immersed in the liquid helium 2 having a temperature of 77k, wherein a superconductive critical current of approximately 1 OOA is obtained.
