摘要：

The high T(c) superconductor of nominal composition Bi1.5-Pb0.5-Ca2-Sr2-Cu3-O(x) was prepared by solid-state reaction method. The upper critical field H(c2) of the material with a zero-resistance transition at 110 K was investigated by observing variations in resistance with temperature down to 90 K and with a magnetic field up to 7T. The slope of H(c2) with temperature was about -0.41 T/K for zero resistance transition and -6.86 T/K for onset of superconductivity. H(c2) values at 0 K were estimated to be 31.3 T and 563 T for zero-resistance transition and onset of superconductivity respectively.
