Abstract

The electronic structure of Fe₃Al is studied by X-ray absorption near-edge spectrum (XANES) at the Fe K edge. The XANES spectrum is compared with that calculated by theory. The experimental XANES features for this intermetallic compound reflect the Fe-p unoccupied density of states (DOS). The magnetic moments and the DOS at the Fermi energy at different atomic sites and spins are calculated and compared with experimental and other theoretical values. The number of Fe d electrons in Fe₃Al is calculated to be 6.25.
