摘要：

The paper presents a magnetic and morphological characterization of iron- and iron-carbide-based nanopowder obtained by the laser synthesis from a sensitized gas phase mixture containing acetylene and iron pentacarbonyl vapor. The analysis was performed on the as-prepared material and the annealed material. We report here the results of TEM, XRD, Mossbauer and magnetic measurements. Phase transformations taking place during annealing when core-shell-like nanostructures appear are discussed. (C) 2004 Published by Elsevier B.V.
