Magnetic circular dichroism of 3d5/2 → 2p3/2 resonant inelastic X-ray scattering at the Ho LIII-edge in Ho3Fe5O12

Magnetic Circular Dichroism (MCD) of Resonant Inelastic X-ray Scattering (RIXS) of 3d(5/2) --> 2p(3/2) decay (Ho L alpha (1)) was measured at the Ho L-III-edge in Ho3Fe5O12. The MCD-RIXS, in which the intermediate state has the 2p4f(n+1) configuration due to the quadrupolar transition of 2p --> 4 (f) over bar, 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).
