Description	V článku se zabýváme morfologickou charakterizací nanoprášku obsahujícího Fe a Fe(x)C(y) nanočástice. Nanoprášek byl vyroben laserovou pyrolýzou plynných reaktantů. Jakožto plynné prekurzory byly použity acetylén a páry pentakarbonylu železa. Analyzován byl jak syntetizovaný nanoprášek tak i nanoprášek žíhaný při 800°C. Uvádíme výsledky analýzy TEM, XRD, Mössbauerovy spektroskopie a magnetických měření. Diskutujeme fázové trasformace probíhající při žíhání nanoprášku jež vedou ke vzniku nanočástic se strukturou jádro-slupka. (cs) We present magnetic and morphological characterization of iron- and iron-carbide- based nanopowder obtained by the laser synthesis from sensitized gas phase mixture containing acetylene and iron pentacarbonyl vapors. The analysis was performed on the as-prepared material and the annealed material. The results of TEM, XRD, Mössbauer and magnetic measurements are reported. Phase transformations taking place during annealing of the nanopowder when core-shell nanoparticles appear are discussed.
