摘要：

We have fabricated and measured cylindrical superconducting current leads composed of a Y1Ba2Cu3O7 (YBCO) and Bi(2-x)Pb(x)Sr2Ca2Cu3O10 (Pb-BSCCO), approximately 20 cm long and 1 cm2 cross section. A steady state, dc, critical current of 170 (230) amperes at a temperature of 77 K was measured for YBCO (Pb-BSCCO) using a voltage criterion of 2 x 10(-7) volts/cm (rho = 8 x 10(-10) ohm-cm). This current was limited by the current-induced, self magnetic field. At a temperature of 63 K this current increased to approximately 390 (465) amperes. The character of the magnetic field dependence of the critical current and the shape of the current induced voltage curves are different for the two materials.
