Abstract
AbstractWe 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 °C: HC = 42.0 kA m−1; σR = 31.2 A m2 kg−1; σS = 95.7 A m2 kg−1 (at 1200 kA m−1). The Curie temperature TC was 227 °C. Thermally induced phase transformations are discussed. Copyright © 2006 John Wiley & Sons, Ltd.
