Abstract
Fe-N films were prepared by ion-beam-assisted deposition at different temperatures. The composition, structure and magnetic properties of th e films were investigated by Rutherford backscattering spectrometry (R ES), X-ray diffraction (XRD) and with vibrating sample magnetometer (V SM). The results of XRD indicated that the films consisted of alpha-Fe , gamma'-Fe4N and epsilon-Fe2-3N, or mixtures of these phases, accordi ng to different N/Fe atomic arrival ratios. It was observed that the f ilm of alpha-Fe with supersaturated nitrogen exhibited a larger M(s) t han that of bulk iron. However, its H-c was too large to be used as so ft magnetic film.
