We have studied the temperature dependence of the photoemission spectra of La1−xSrxMnO3(x=0.0, 0.2, and 0.4) and found that the spectral line shape dramatically changes in the entire valence-band region, particularly for x=0.2 and 0.4. By contrast, the spectra of La0.6Sr0.4CoO3show no significant temperature dependence. From comparison between the temperature- and composition-(x) dependent spectral changes and the temperature-composition phase diagram of La1−xSrxMnO3, we suggest that the changes are related to the degree of hole localization on oxygen p orbitals, which is influenced by electron-lattice coupling and magnetic correlations.
