Abstract
We have studied the electronic structure of ferrimagnetic single crystals by means of soft x-ray absorption spectroscopy (XAS), x-ray absorption magnetic circular dichroism (XMCD), and resonant soft x-ray inelastic scattering (RIXS). We have successfully observed the XMCD signals for all the constituent elements. The Mn XAS and XMCD spectra are reproduced by spectral simulations based on density-functional theory, indicating the itinerant character of the Mn states. On the other hand, the V electrons are rather localized since the ionic model can qualitatively explain the V XAS and XMCD spectra. This picture is consistent with local excitations revealed by the V RIXS.
