Abstract
The magnetic field dependence of the resistivity and susceptibility of multiphase Bi-Sr-Ca-Cu-O compounds exhibiting transport and diamagnetic anomalies at ≃115 and ≃75 K are reported. The field dependence of the latter yields values of Hc1 and dHc2dT(T=Tc) very similar to those found for the Y(R)Ba2Cu3O7−x family of Cu perovskitelike superconductors. The field dependence of the above-100-K region strongly suggests that bulk superconductivity, as opposed to filamentary or fluctuation behavior, dominates at these temperatures.
