摘要：

Magnetic nanoparticles of Fe and Co were synthesized by Chemical Vapor Condensation (CVC) using the precursors of iron carbonyl (Fe(CO)(5)) and cobalt carbonyl (Co-2(CO)(8)) as the sources under a flowing helium atmosphere. Characteristics were investigated systematically by means of XRD, HRTEM and VSM. Typical particle sizes are on the order of 5 to 13 nm with uniform dispersion. A correlation between the process parameters of CVC and the resulting microstructure of the nanoparticles was investigated. Mechanism of forming the nanoparticles and the direction to improve the magnetic properties were discussed. (C) 2001 Acta Materialia inc. Published by Elsevier Science Ltd. All rights reserved.
