Abstract
The x-ray magnetic circular dichroism (XMCD) spectra of ${\text{CeFe}}_{2}$ at the $\text{Ce}\text{ }{L}_{2,3}$, ${M}_{4,5}$, $\text{Fe}\text{ }K$, and ${L}_{2,3}$ edges are investigated theoretically from first principles, using the fully relativistic Dirac linear muffin-tin orbital band-structure method. The electronic structure is obtained with the local spin-density approximation. The origin of the XMCD spectra in the compound is examined. The core hole effect in the final states has been investigated using a supercell approximation. It improves the agreement between the theory and the experiment at the $\text{Ce}\text{ }{M}_{5}$ edge. However, it has a minor influence on the shape of the $\text{Ce}\text{ }{L}_{2,3}$ XMCD spectra.
