Abstract
The electronic structures of ordered and disordered transition metal alloys are described in a tight-binding scheme. Charge transfer and magnetism are treated within a self-consistent Hartree-Fock model. The authors show that the rigid band splitting fails to take account of the ferromagnetism of these compounds. The densities of states of FeCo and Ni3Fe are found to be more sensitive to order than the ferromagnetic properties. Energetic calculations are performed giving an estimation of the ordering energy, and comparisons are made with experimental results.Keywords
