MTiO$$_{3}$$(M=Mn, Co, FE, Ni)についてTi2p発光測定を行った。FeTiO$$_{3}$$では弾性散乱ピークから2.5eVおよび4.5eVおよびに構造がみられたが他では4.5eVだけだった。これについてモデル計算を行い起源がTi-Mの電荷移動であることを解明したので報告する。

In this study, we have measured the Ti 2p edge resonant inelastic X-ray scattering spectra of MTiO3 (M= Mn, Fe, Co, and Ni) in order to investigate the intermetallic M 3d-Ti 3d charge transfer. We found the peak around -4.5 eV in the energy loss scale for all MTiO$$_{3}$$ and additionally found that only FeTiO$$_{3}$$ has a peak at at -2.5 eV. Those peaks are attributed to the M 3d-Ti 3d charge transfer.
