Effects of order on the electronic structure of ferromagnetic transition metal alloys: application to FeCo and Ni_3Fe

Résumé

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. We show that the rigid band splitting fails to take account of the ferromagnetism of these compounds. The densities of states of $FeCo$ and $Ni_3Fe$ 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.
