Aj. Dyakonov et al., MAGNETIC-MATERIALS BASED ON IRON DISPERSED IN GRAPHITIC MATRICES .2. HIGH-TEMPERATURES AND MESOPHASE PITCH, Journal of magnetism and magnetic materials, 167(1-2), 1997, pp. 115-122
Ferromagnetic materials based on iron incorporated into pitch were syn
thesized, and characterized by magnetic methods (Faraday), Mossbauer s
pectroscopy, SEM, and XRD. A graphitic-type structure was observed to
form at 350-1650 degrees C. The important role of a mesophase structur
e of a pitch-precursor in the iron carbonyl absorption and anisotropic
structure of the resulting iron containing material was found.
