The particles with well-defined facets consisting of Fe3O4 and gamma-Fe2O3 and self-assembled into long chains were produced at the power of 360 W. At higher power of 440-460W the deposit contained significant amount of multi-walled carbon nanotubes covered by iron oxide nanoparticles. The diameter of CNTs was 8-20 nm. The particles had Fe3O4 and/or alpha-Fe2O3 cores of spherical shape covered by a thin layer of carbon. (C) 2008 Elsevier B. V. All rights reserved.
