Summary

The magnetic properties of Fe16N2, bcc iron and bct iron were studied using the linear muffin tin orbital method in combination with the atomic sphere approximation (LMTO-ASA). The following results were obtained: The magnetovolume effect is the most important for the large magnetic moment of Fe16N2. The magnetic moment of iron increases with the distance from the nitrogen. The nitrogen atom plays a role in expanding the lattice. The effect of local lattice relaxation of the iron atoms that are first- and second-nearest neighbors to a nitrogen atom was examined.
