| Description
| - We describe the phase composition and magnetic properties of the nanocomposite based on iron/graphite core-shell structured nanoparticles. 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°C 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. Mössbauer spectroscopy was used to observe a qualitative change in phase composition.

- V článku popisujeme fázové složení a magnetické vlastnosti nanokompozitu obsahujícího nanočástice se strukturou jádro-slupka. Jádro částic je tvořené alfa-Fe a slupka je z grafitu. Tyto nanočástice vznikly žíháním nanoprášku vyrobeného laserovou pyrolýzou plynných reaktantů. Nanoprášek, který byl syntetizován z plynných prekurzorů obsahujících prvky Fe, C, N, byl studován pomocí TEM, XRD a magnetických měření. Nanoprášek byl následně vyžíhán při 800°C ve vakuu, přičemž došlo k nukleaci a růstu alfa-Fe nanočástic. Přítomnost alfa-Fe nanočástic se středním průměrem 40 nm ve vyžíhaném nanoprášku byla dokázána XRD a TEM analýzou. Mössbauerova spektroskopie byla použita pro upřesnění fázového složení syntetizovaného i vyžíhaného nanoprášku. (cs)
