The electronic structures of paramagnetic and ferromagnetic ScFe. are calculatedself-consistently using the KKR method in the framework of the local-spin-density ap-proximation for the exchange-correlation potential. The general electronic structuresare similar for both of the atom Fe(2*) at the 2a sites and the atom Fe(6#) at the 6hsites. However the difference is seen near the Fermi level in the densities-of-state of clbands between Fe(2a) and Fe(6#). This difference induces a small difference in themagnetic moments between the two Fe; the values are 1.40?./Fe(2*) and 1.46p./Fe(6#). The atom Sc also carries a magnetic moment of 0.27 p./ Sc with the directionopposit to the moment of Fe.
