摘要

在与2p 3/2激发共振的入射光子能量下，观察到铁磁性EuO (tc569k)在b2,15荧光中的磁圆二色性。二色性主要是局域态4f电子与终态4d核空穴之间的交换作用。通过原子多重计算得到的2p4d发射光谱形状与实验数据吻合较好。

Magnetic circular dichroism in the 2p4d x-ray emission of EuO

Magnetic circular dichroism is observed for ferromagnetic EuO (T C 569 K) in the b2,15 fluorescence at incident photon energies resonant with the 2p 3/2 excitation. The dichroism is dominated by exchange interac-tion between the localized 4 f electrons and the final state 4d core hole. The spectral shapes obtained by atomic multiplet calculations for the 2p4d emission show good agreement with the experimental data.
