This nanocomposite was prepared by a two-step procedure: in the first step, the original Fe-C-N based nanopowder was synthesized by the method of laser pyrolysis of gas phase reactants, and subsequently in the second step, it was heated up to 800\u00B0C in vacuum. Annealing in vacuum induced the formation and growth of iron/graphite core-shell structured nanoparticles. Both the originally synthesized Fe-C-N based nanopowder and the annealed nanopowder were characterized by TEM, XRD and magnetic measurements. 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 to observe a qualitative change in phase composition." . . . "Voicu, I." . "8"^^ . . . "Vysok\u00E9 u\u010Den\u00ED technick\u00E9 v Brn\u011B.
