Abstract

The electronic structures of perovskite SrMn _1-x Mo _xO ₃ (0≤x≤0.5) have been investigated by employing soft x-ray absorption spectroscopy (XAS). Mn2p XAS shows the systematic change in the valence states of Mn ions in SrMn _1-xMo _xO ₃ due to the substitution of hexavalent Mo ⁶⁺ (4 d ⁰) ions. With increasing x, the valence states and the spin configurations of Mn ions change from high-spin (HS) Mn ⁴⁺ for x=0, to HS Mn ³⁺ (t _2g ³ ↑ e _g ¹ ↑) for x=0.3, and HS Mn ²⁺ (t _2g ³ ↑ e _g ² ↑) for x=0.5. The measured Mn2p XAS spectra are described well with the configuration interaction (CI) cluster model, including the Jahn-Teller distortion effect for Mn ³⁺ ions. The combination of the findings of Mn2p XAS and the CI calculations provides the complete picture of the electronic structures of SrMn _1-xMo _xO ₃ for 0≤x≤0.5.
