"Two samples of nanopowders containing superparamagnetic Fe3C and Fe3O4/gamma-Fe2O3 particles and carbon black were synthesized by the method of laser-induced homogeneous pyrolysis of gaseous precursors. Both were characterized by XRD, HR-TEM, M\u00F6ssbauer spectrometry and standard magnetic measurements. The mean crystallite size of Fe3C was 3 nm for the first sample and 10 nm for the second sample. Fe3C phase in both samples exhibited reduced Curie temperature and smeared ferromagnetic-paramagnetic transition. After annealing of the samples at 800\u00B0C for 30min the Curie temperature of the recrystallized Fe3C phase in both samples was 214\u00B0C (standard bulk value)."@en . "42" . . . .
