The Fe4N displays a remarkably rich behaviour that has attracted the attention of applied and basic researchers in the last 80 years. The earliest interest on the synthesis and study of  properties was motivated by its possible application as a catalyst for the production of ammonia and for its role in the surface treatment of steels with ammonia [1]. Later, it was considered as a material for high-density magnetic recording component in thin film devices. Recently, an extensive study of this material has been performed by different techniques such as Mössbauer Spectroscopy[2], Neutron diffraction [3] and first principles calculations [8].
