Magnetic circular dichroism of 3d_5/2 → 2p_3/2 resonant inelastic X-ray scattering at the Ho L_III-edge in Ho₃Fe₅O₁₂

Magnetic Circular Dichroism (MCD) of Resonant Inelastic X-ray Scattering (RIXS) of 3d_5/2 → 2p_3/2 decay (Ho Lα₁) was measured at the Ho L_III-edge in Ho₃Fe₅O₁₂. The MCD-RIXS, in which the intermediate state has the 2p4fⁿ⁺¹ configuration due to the quadrupolar transition of 2p → 4f̄, was also observed at the pre-edge region of the Ho L_III-edge. The obvious superposition of two peaks, which comes from the high-energy off-resonant Raman scattering and the fluorescence, could be found in both the RIXS and the MCD-RIXS when the energy of the incoming X-ray was 7eV higher than the white line. The dependence of the integration of the MCD-RIXS spectra on the incident x-ray energy could roughly reproduce the MCD of X-ray absorption spectra (XAS).
