Description	Fe-based nanoparticles were prepared by laser pyrolysis method using a cross-flow reactor in which the CO2 laser radiation orthogonally crosses with the stream of Fe(CO)5, C2H2, and C2H4 gases. The as-synthesised powder was characterised by HRTEM, XRD, Mössbauer spectroscopy, and low- and high-temperature magnetic measurements. The as-synthesised powder consisted of a-Fe and Fe3O4/g-Fe2O3 nanoparticles embedded in a pyrolytic carbon matrix. The XRD pattern of the sample exhibited broad peaks. The crystallite size dXRD was estimated using the Scherrer formula and it was 1.8nm for a-Fe and 1.6nm for pyrolytic carbon. The assynthesised nanopowder was superparamagnetic. The blocking temperature was determined from the maximum of the ZFC curve and it was 32 K. After the sample had been cooled down to 4K, the Mössbauer-Lamb factor f strongly increased.
