摘要	200 nm Fe-N thin films deposited on glass substrates by RF sputtering were vacuum annealed at 250-350degreesC under 12000 A/m magnetic field, Heat treatment was effective in improving the soft magnetic properties of the Fe-N film. When the nitrogen content was in the range of 5-7 at. %, the thin films consisted of alpha' + alpha" after heat treatment and had excellent soft magnetic properties of 4piM(s) = 2.4 T, H-C < 80 A/m, mu(r) = 1500 under 2-10 MHz. The properties of the films meet the needs of a write head material used in the dual element GMR/inductive heads. The fromation mechanism and lattice constants of the alpha' phase in Fe-N thin film are different from Jack's results obtained from gamma-->alpha' transformation in bulk samples. The linear relationship between a, c and C-N for thin film was obtained as c = 2.866 + 1.559 C, a = 2.866 + 0.181 C.
