"We describe the Fe3C-based nanopowder obtained through the laser-induced pyrolysis of the gas mixture of Fe(CO)5 and C2H4. This ferromagnetic nanopowder was characterized by XRD, HRTEM and magnetic measurements. Aggregated core-shell nanoparticles were identified in the nanopowder; Fe3C cores were coated with pyrolytic carbon. The mean coherence domain size estimated by the Scherrer formula was 18 nm. Basic magnetic characteristics were measured at 20 \u00B0C: HC = 42.0 kA/m; \u03C3_r = 31.2 A m2/kg; \u03C3_s = 95.7 A.m2/kg (at 1200 kA/m). The Curie temperature Tc was 227 \u00B0C. Thermally induced phase transformations are discussed." . "Fe3C nanopr\u00E1\u0161ek syntetizovan\u00FD laserovou pyrol\u00FDzou a jeho chov\u00E1n\u00ED p\u0159i \u017E\u00EDh\u00E1n\u00ED"@cs .
