| 内容記述 | The valence distribution and local structure of Bi1−xPbxNiO3 (x ≤ 0.25) were investigated by comprehensive studies of Rietveld analysis of synchrotron X-ray diffraction (SXRD) data, X-ray absorption spectroscopy (XAS), hard X-ray photoemission spectroscopy (HAXPES), and atomic pair distribution function (PDF) analysis of synchrotron X-ray total scattering data. Disproportionation of Bi ions into Bi3+ and Bi5+ accompanied by an intermetallic charge transfer between Bi5+ and Ni2+ was observed for all the samples, but it was a longranged one with distinct crystallographic sites in the P1̅ triclinic structure for x ≤ 0.15, while the ordering was short-ranged for x = 0.20 and 0.25. In the case of the higher Pb concentration, the long-range order does not grow due to the obstruction of the substituent Pb and a macroscopically glassy charge distribution appears. | |||||
