Abstract

The electronic structure and x-ray magnetic circular dichroism (XMCD) spectra of UGe2 at the U N-4,N-5, N-2,N-3 and Ge K and L-2,L-3 edges are investigated theoretically from first principles, using the fully relativistic spin-polarized Dirac linear muffin-tin orbital (LMTO) band structure method. The electronic structure is obtained with the local spin-density approximation (LSDA), as well as the LSDA+ U method. The origin of the XMCD spectra in the compound is examined.
