摘要
We study the preparation and properties of metallic iron particles, synthesized by thermal decomposition of Fe(CO)(5) in the presence of a stabilizer. By varying the iron carbonyl/polymer ratio, the particle size can be varied from 2 to 10nm. Particles are characterized by magnetization measurements, transmission electron microscopy (TEM), small angle X-ray scattering and cryo-TEM. Cryo-TEM pictures show linear structures of particles. From susceptibility measurements, it is seen that particles oxidize fast on exposure to air. (C) 2002 Elsevier Science B.V. All rights reserved.
