Abstract

Electronic structures of perovskite oxides of SrMn_1-xMo _xO₃ in the Mo-rich regime (x≥0.5) have been investigated by employing soft x-ray absorption spectroscopy (XAS). Mn 2p XAS spectra of SrMn_1-xMo_xO₃ indicate that the valence states of Mn ions are divalent and that they remain nearly unchanged for x≥0.5. On the other hand, the Mo 3p XAS spectra of SrMn_1-xMo _xO₃ show some changes, suggesting that the valence states of Mo ions decrease with increasing x for x≥0.5. These conclusions are supported by the unoccupied Mn 3d and Mo 4d states, observed experimentally in the O 1s XAS spectra of SrMn_1-xMo_xO₃.
