Abstract

In this study, the relationship among magnetic properties, Aerosol Deposition (AD) conditions and microstructures in Sm-Fe-N AD films were investigated. The maximum thickness of 145 μm was obtained in the AD conditions of gas flow rate (gfr) = 6 L/min for 10 min. The density of Sm-Fe-N films were in the range of 5.43-6.24 g/cm³, which were 71-81 % of the X-ray density of the Sm₂Fe₁₇N₃ compound reported (7.67 g/cm³). The Sm-Fe-N AD films showed remanence in the range of 0.38-0.42 T, which were 61-68 % of that of Sm-Fe-N host powder (0.62 T). The coercivities increased from 1.16 to 1.74-1.79 T after the deposition because the grain size decreased from 1.94 to 0.32 μm.
