. "We are reporting the phase composition and magnetic properties of the core-shell structured iron/graphite nanoparticles formed during annealing of a nanopowder prepared by the laser pyrolysis of gas phase reactants. The originally synthesized Fe-C-N based nanocomposite powder was characterized by TEM, XRD and magnetic measurements. The nanopowder was heated up to 800\u00B0C in vacuum. The presence of iron nanoparticles with the mean diameter of 40 nm in the annealed state of the nanopowder was proved by XRD and TEM analysis. M\u00F6ssbauer spectroscopy was used for the characterization of the synthesized/annealed nanopowder to prove the qualitative change in the phase composition." . "[4BE8D7D3BA09]" . . . .
