Abstract

Iron nitride and iron carbonitride (ICN) ultrafine particles (20-80 nm in size) have been synthesized by laser-induced pyrolysis of the Fe(CO)₅-NH₃-C₂H₄ system. The oxidation behavior, surface morphologies, and structural characteristics as well as magnetic properties of these particles are reported and discussed. It is found that the presence of very thin carbon coating (1-2 nm) on the ICN particles plays an important role in preventing the oxidation of the particles. Accordingly, the ICN ultrafine particles exhibit higher saturation magnetization (142 emu/g) than the iron nitride ones (124 emu/g).
