ε-Fe3N: magnetic structure, magnetization and temperature dependent disorder of nitrogen

Using the augmented spherical wave method (A. S. W.) we calculate the electronic and magnetic structures of Fe 4 N and Mn 4 N. Both nitrides are found to order magnetically exhibiting ferro- and ferrimagnetic spin alignment respectively. The magnetic moments found are in good agreement with neutron data. Both systems can be described via covalent magnetism. Comparison with Goodenough's phenomenological model as well as with Heusler alloys is given Calcul des structures electroniques et magnetiques en utilisant la methode de «l'onde spherique augmentee». Les deux composes s'ordonnent magnetiquement avec un alignement ferro- et ferrimagnetique. Les valeurs des moments magnetiques sont en bon accord avec celles de la litterature. Comparaison avec le modele phenomenologique de Goodenough et avec les alliages de Heusler
