Abstract : Using the augmented spherical wave method A.S.W. we calculate the electronic and magnetic structures of Fe4N and Mn4N. 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. A comparison with Goodenough-s phenomenological model as well as with Heusler alloys is given.
