The electronic energy band structure for MnPt., FePd. and PtFe., which area typical ferromagnetic transition metal alloy having the AuCu3-type crystalstructure, is calculated by a self-consistent, spin-polarised APW method with the!ocal-spin-density approximation. The relativistic effects except the spin-orbitinteraction are taken into account. A fairly large exchange splitting, about twicethat of the Fe metal, is found to occur in the Mn and the Fe d bands of thesealloys. Calculated results for the density of states and the spin magnetic moment ofeach constituent atom agree quantitatively well with recent experimental results.
