Reactive rf-sputter deposition was applied on Fe-Al-N ternary thin film deposition. New wurtzite-type solid solution of Al1-xFexN (x<30atm%) was observed on all as-deposited films. Defect rocked salt-type γ"-FeN coexisted in the films with composition above the solid solution limit. The as-deposited films were paramagnetic. Granular film where α-Fe dispersed in amorphous matrix was obtained by annealing of the films with chemical composition above the solid solution limit in H2 flow at 500°C. They showed soft ferromagnetic behavior. Asdeposited film with composition below the solid solution limit was thermally stable in the annealing at 500°C.
