5f states in UGa2 probed by x-ray spectroscopies
Original language description
The ferromagnet UGa2 was investigated by x-ray absorption spectroscopy and x-ray magnetic circular dichroism (XMCD) experiments at the U–M4,5 and Ga–K edges. The position of the U–M4 white line, determined in the high-energy resolution fluorescence detection XAS, suggests that UGa2 is neither a localized 5f2 nor an itinerant system with 5f occupancy close 3. The analysis of the acquired M4,5 XANES and XMCD spectra indicates the 5f occupancy close to 2.5 and a large orbital magnetic moment of the uranium 5f states that is partly compensated by the antiparallel spin moment. Several methods based on density-functional theory were applied and the obtained results were compared with experimental observations. Only electronic structure methods taking appropriate care of orbital magnetism and related atomic multiplet effects can successfully describe all considered properties.
