| Abstract: | Abstract We have measured the electrical resistance R of a sintered, two-phase, high-TC superconductor with the nominal composition BiSrCaCu2Ox, as a function of T and p. We find d(lnR)/dp ? -0.06 GPa?1 at 295 K, while dTC/dp is 2.5 K/GPa for the phase with Tc ? 76 and 2 K/GPa for that with TC ? 106 K. |
