概要
- 論文の詳細を見る
Orbitally ordered states of a Ti t_<2g>-electron in Y_<1-x>Ca_xTiO_3 (0 < x ≤ 0.5) have been systematically investigated by the resonant X-ray scattering (RXS) technique near the Ti K-edge. The RXS intensities at 1s → 3d transition energy (pre-edge) reflecting the 3c?-orbital ordering markedly decrease with increasing Ca concentration toward the ferromagnetic-paramagnetic phase boundary (x_<FP> 〜 0.15). The intensity remaining above x<FP> decreases gradually and almost disappears at the metal-insulator transition x_<MI> 〜 0.4). Namely, it is suggested that the orbital ordering is strongly suppressed toward x_<FP>, and vanishes at x_<MI>. The Ca concentration dependence of the Jahn-Teller distortion determined by X-ray structural analysis is consistent with the orbital state obtained by the RXS experiment.
