Abstract

Samples of the Bi_1.8Pb_0.2Sr₂CaCu₂O _8-δ system with different oxygen concentrations were prepared by annealing the corresponding ceramic sample in various conditions. The normal-state properties were investigated by means of X-ray diffraction (XRD), resistivity, thermoelectric power (TEP), and specific heat. Analyses of these data demonstrate that a possible phase segregation exists in some samples, i.e., the Bi_1.8Pb_0.2Sr₂CaCu₂O _8-δ phase with lower carrier concentrations separates into oxygen-rich superconducting domains and oxygen-poor superconducting domains. The anomalous properties of the normal state are discussed in the paper.
