Abstract Fe-N films over a wide compositional range have been prepared by the reactive sputtering method. Fe-N sputtered films were composed of a single or two phases such asζ-Fe2N,ε-Fe3.02N,γ′-Fe3.82N,γ′-Fe4N andα-Fe; however, an unknown phase was observed at a higher nitrogen pressure. A remarkable preferred orientation of theε-Fe3.02N (110) plane parallel to the film surface was observed. The Curie temperature of the sputtered γ′-Fe3.82N sample was 490° C, which was almost the same as that ofγ′-Fe4N prepared by metal nitriding. The saturation magnetization,σ s, of the sputtered Fe-N samples decreased from 151.8 to 42.4 e.m.u.g−1 with increasing nitrogen content from 7.94 to 24.87 at%, and its coercive force,1 H c was found to lie in the range 150 to 600 Oe in the powder form at room temperature.
