摘要:

我们报告了一个铜K-边共振非弹性X射线散射(RIXS)研究的轨道激发KCuF 3。通过对散射光子的偏振分析,我们发现eg轨道之间的激发和t2 g到eg轨道之间的激发具有明显的偏振依赖性。各自的激发的偏振依赖性解释的基础上的RIXS过程,产生观察激发的必要条件的对称性的唯象考虑。此外,我们表明,轨道激发在我们的实验分辨率是色散。

英文摘要:

We report a Cu K-edge resonant inelastic x-ray scattering (RIXS) study of orbital excitations in KCuF3 . By performing the polarization analysis of the scattered photons, we disclose that the excitation between the eg orbitals and the excitations from t2g to eg exhibit distinct polarization dependence. The polarization dependence of the respective excitations is interpreted based on a phenomenological consideration of the symmetry of the RIXS process that yields a necessary condition for observing the excitations. In addition, we show that the orbital excitations are dispersionless within our experimental resolution.
