Effect of an applied field during film deposition on magnetic properties of aerosol-deposited (AD) Sm-Fe-N films was investigated. By aligning the two magnets with facing the opposite poles, a magnetic field of 0.15 T can be applied perpendicular to the film. The thickness of AD film decreased with increasing applied field. However, relatively large thickness of 94 μm was obtained at 0.15 T. The remanence measured in the perpendicular direction increased from 54.5 to 61.3 Am2/kg by applying magnetic field. In the case of using a solenoid coil, a magnetic field of 0.21 T can be applied perpendicular to the film. The thickness of AD film also decreased, however, the AD film shows thickness of 65 μm at 0.21 T. The remanece in the perpendicular direction increased from 54.5 to 58.6 Am2/kg with increasing applied field. Therefore, it is concluded that the AD film can be oriented perpendicular to the film plane by applying a magnetic field and show high remanence with maintaining large thickness.
