N2 - The effect of charge ordering of (Formula presented) and (Formula presented) ions on bonding features between oxygen (Formula presented) and manganese (Formula presented) orbitals in (Formula presented) (Formula presented) was studied along with the oxygen K edge by electron-energy-loss spectroscopy. A peak at 529 eV in the oxygen K edge was found to be sensitive to the manganese (Formula presented) hole content via strong hybridization between oxygen (Formula presented) and manganese (Formula presented) orbitals. It was demonstrated that the intensity was slightly reduced with the charge ordering in (Formula presented) This effect was rationalized by considering such a mechanism that the strong hybridization with manganese (Formula presented) orbital was weakened as a result of the lattice distortion caused by the charge ordering, which was detected by a precise electron-diffraction method with energy-filtering and imaging plates.
