Abstract
The magnetization of N and has been calculated from first principles, employing the full-potential linearized-augmented-plane-wave method. The calculated magnetization of N is in fair agreement with experimental results. The differences between calculated and experimental values are at most 10%. The calculated magnetization of , however, is 30% smaller than the huge value of ≃3.2 T reported recently for iron-nitride thin films, which were characterized as single-phase . Based on this result and on a comparison between calculated and experimental hyperfine fields we conclude that the α’’- phase cannot be responsible for the ultrahigh magnetization reported for single-phase iron-nitride thin films.
