摘要

We are reporting the core-shell structured iron/graphite nanoparticles formed during annealing of the nanopowder prepared by laser pyrolysis of gas phase reactants. The originally synthesized Fe-C-N based nanocomposite powder has been characterized by TEM, XRD and magnetic measurements. Nanopowder was heated up to 800℃ at ～ 1 Pa vacuum. Presence of iron nanoparticles with the mean diameter of 40 nm in the annealed state of nanopowder was proved by XRD and TEM. Moessbauer spectroscopy was used for characterization of the synthesized/annealed nanopowder.
