nanoparticles are synthesized by reaction of Fe(CO)5 and NH3 gas using synthetic oil as the carrier liquid (170—190 °C) and characterized by XRD, XPS, TEM, and mag-netization measurements. The saturation magnetization and Curie temperature of the ε-Fe3N nanoparticles decrease with decreasing particle size and are lower than those of the bulk material. However, the coercitivity of the nanoparticles increases with decreas-ing particle size. — (HUANG*, W.; WU, J.; GUO, W.; LI, R.; CUI, L.; J. Alloys Compd. 443 (2007) 1-2, 48-52; Div. Funct.
