Abstract:
We present measurements of resonant x-ray Raman scattering at the Co L-2,L-3 edges in CoFe2O4 with circularly polarized x-rays incident perpendicularly to the magnetization direction. We have selected the scattering channel having a 3s hole in the final state. The L-3 scattering gives dichroism spectra very much dependent on the excitation energy showing a typical Raman regime with a very small component independent of the excitation energy. Calculations based on a cluster ionic model compare well with the measurements. The calculations include configuration interaction in the ground state (to include a noninteger 3d occupation) and in the final state (to account for the two possible configurations having either one 3s hole or two 3p holes).
