Different routes to charge disproportionation in perovskites-type Fe oxides
J. Matsuno, T. Mizokawa, A. Fujimori +3
Iron perovskites CaFeO_3 and La_{0.33}Sr_{0.67}FeO_3 show charge disproportionation, resulting in charge-ordered states with Fe^{3+}:Fe^{5+} =1:1 and =2:1, respectively. We have ma…

Chemical potential shift in La(1-x)Sr(x)MnO(3): Photoemission test of the phase separation scenario
J. Matsuno, A. Fujimori, Y. Takeda +1
We have studied the chemical potential shift in La(1-x)Sr(x)MnO(3) as a function of doped hole concentration by core-level x-ray photoemission. The shift is monotonous, which means…
