XPS Study on the Formation Process of the High-Tc Phase in the Bi-Pb-Sr-Ca-Cu-O System

Year: 1989

Type: article

Abstract: X-ray photoemission spectroscopy (XPS) measurements were carried out to investigate the changes in the Cu ion valency through the formation of the high-T c phase in the Bi-Pb-Sr-Ca-Cu-O superconducting system. The Cu2+ composition increased rapidly in the initial stages of sintering and became saturated, whereas the Cu+ and Cu3+ compositions showed a systematic change, within a certain sintering time, dependent on the sintering temperature. It was found that these changes in the Cu ion valency reflect the structural change in the formation of the high-T c phase in this system.
