Abstract

We calculate X-ray magnetic circular dichroism (XMCD) spectra in the Lu L3 edge of ferromagnetic compounds Lu₂Fe₁₄B and LuFe ₂, and in the Ce L3 edge of a mixed valence compound CeFe ₂. The calculated results are in good agreement with the available experimental ones, although spectral structures are mostly smeared out by the large lifetime broadening of the 2p3/2 core hole. We then calculate the spectrum of L3-M5 resonant X-ray emission spectroscopy (RXES) and its MCD (MCD-RXES) for these materials, and predict theoretically that the experimental observation of excitation spectra of MCD-RXES is a powerful tool to detect fine structures of XMCD beyond the lifetime broadening of the 2p3/2 core hole.
