对混合价态铁磁化合物CeFe 2的磁圆二色性进行了理论计算，得到了磁圆二色性共振X射线发射光谱（MCD-RXES）和磁圆二色性X射线吸收光谱（MCD-XAS）.结果表明，CeL 3 -M5 MCD-RXES的激发光谱接近于CeL 3 MCD-XAS的一个较小加宽的版本，这揭示了传统CeL 3 MCD-XAS测量所看不到的源于Ce 4f 2组态的结构.
Theoretical calculations are performed for magnetic circular dichroism in resonant x-ray emission spectroscopy (MCD-RXES) and magnetic circular dichroism in x-ray absorption spectroscopy (MCD-XAS) in a mixed valence ferromagnetic compound CeFe 2 . It is shown that the excitation spectrum of Ce L 3 – M 5 MCD-RXES is close to a less broadened version of the Ce L 3 MCD-XAS, which reveals the structure originating from the Ce 4 f 2 configuration invisible by the conventional Ce L 3 MCD-XAS measurements.
