Investigation on magnetic carbon nanofoam composites

Abstract

Magnetic carbon nanofoam composites have been synthesized by employing electric arc discharge using nano-crystalline 1% by weight cobalt ferrite particles as catalyst. The material formed is a short-range fluffy type arrangement of carbon embedded with nano-magnetic particles. The volume percent of carbon is ~ 85% in the composite material and the density is ~ 0.8 g/cm³. Material has been characterized for its physical properties like structural, magnetic, shape and size distribution by XRD, TEM, SAXS, EPR and VSM measurement techniques. The prepared composite has low density, electrically conducting and soft magnetic properties. The developmental studies of magnetic carbon nanofoam process have been described.
