Description
| - We describe the Fe3C-based nanopowder obtained by the laser-induced pyrolysis of the gas mixture of Fe(CO)5 and C2H4. This single ferromagnetic phase nanopowder was characterized by XRD, HRTEM and Mössbauer spectroscopy. Aggregated core-shell nanoparticles were identified in the nanopowder, Fe3C cores are coated with pyrolytic carbon. The mean coherence domain size estimated by the Scherrer formula is 18 nm. Basic magnetic characteristics were measured at 20 °C: Hc = 42.0 kA/m; σ_r = 31.2 A.m2/kg; σ_s = 95.7 A.m2/kg (at 1200 kA/m). The Curie temperature Tc was 227 °C. Thermally induced phase transformations are discussed.

- Popisujeme nanoprášek obsahující Fe3C získaný metodou laserové pyrolýzy plynné směsi Fe(CO)5 a C2H4. Tento nanoprášek s jednou feromagnetickou fází byl studován pomocí RTG, HRTEM a Mossbauerovy spektroskopie. V nanoprášku byly identifikovány agregované nanočástice s morfologií jádro-slupka, přičemž jádro bylo tvořeno Fe3C a slupka byla tvořena pyrolytickým uhlíkem. Střední velikost koherentní domény pro Fe3C byla odhadnuta pomocí Scherrerovy formule na 18 nm. Základní magnetické parametry byly změřeny při 20 °C: Hc = 42.0 kA/m; σ_r = 31.2 A.m2/kg; σ_s = 95.7 A.m2/kg (at 1200 kA/m). Curieova teplota Tc vzorku byla 227 °C. Diskutujeme fázové transformace probíhající ve vzorku při vyšších teplotách. (cs)
