Sm₂Fe_(17)Nx film magnets were prepared using a Sm₂Fe_(17) target in a N₂ gas atmosphere using a Nd-YAG pulsed laser ablation technique. The effect of nitrogen pressure, deposition temperature, pulse time and film thickness on the structure and magnetic properties of Sm₂Fe_(17)Nx film were studied. Increasing the nitrogen pressure up to 5 atm led to the formation of complete Sm₂Fe_(17)Nx compound. Optimized magnetic properties with the nitrogenation temperature in the range 500-530 ℃ could be obtained by extending the nitrogenation time up to 4 hours. Relatively low coercivities of 400~600 Oe were found in Sm₂Fe_(17)Nx films 50~100 ㎚ thick, while a 4πMs of 10~12 kG could be achieved. In-plane anisotropy, which was the basic goal in this study, was achieved by controlling the nitrogenation parameters.
