Electronic excitations in the correlated metal BaTi(0.02)V(0.98)S(3) have been studied using resonant inelastic soft x-ray scattering at the V L edge. The intensities of the intra-atomic d-d(*) excitations and the elastic x-ray scattering feature are found to be temperature dependent, with the intensity increasing with decreasing temperature until saturation is reached near 100 K. The behavior of the spectral features is interpreted as evidence of a shift in the 3d electrons from more band-like states at higher temperature to more localized states at low temperature.
使用共振非弹性软 X 射线散射在 V L 边缘研究了相关金属 BaTi(0.02)V(0.98)S(3)中的电子激发。发现原子内 d-d(*)激发和弹性 X 射线散射特征的强度随温度变化,随着温度降低,强度增加,直到在 100 K 附近达到饱和。光谱特征的行为被解释为 3d 电子从高温下更带状的状态向低温下更局域的状态转移的证据。
