反铁磁钬中E1和E2对L3共振线形状的贡献
E1 and E2 contributions to the L3 resonance line shape in antiferromagnetic holmium
摘要：
详细研究了在L3边缘的底面螺旋反铁磁相中的钬的电偶极（E1：2 p->5d）和四极（E2：2 p->4f）对X射线散射截面的贡献的角度、能量和偏振依赖性。相应的E1和E2散射因子已被提取的实验能量线的形状考虑到第一次分裂偶极共振拟合。使用共振散射因子的虚部检索的XMCD光谱，我们发现定性协议与通过钬箔传输测得的二向色光谱。
英文摘要：
A detailed study of the angular, energy and polarization dependences of the electric dipolar (E1: 2p->5d) and quadrupolar (E2: 2p->4f) contributions to the x-ray scattering cross-section is presented for holmium in its basal plane spiral antiferromagnetic phase at the L3 edge. The corresponding E1 and E2 scattering factors have been extracted from fits to the experimental energy line shapes taking into account for the first time a split dipole resonance. Using the imaginary part of the resonant scattering factors to retrieve the XMCD spectrum, we find qualitative agreement with the dichroic spectrum measured in transmission through a holmium foil.
