Aj. Dyakonov et al., MAGNETIC-MATERIALS BASED ON IRON DISPERSED IN GRAPHITIC MATRICES, .1.SUPERPARAMAGNETIC IRON IN AN AMORPHOUS MATRIX, Journal of magnetism and magnetic materials, 137(1-2), 1994, pp. 11-17
New superparamagnetic, iron-containing materials have been synthesized
from petroleum pitch and Fe2(CO)9. The materials are air-sensitive an
d without protection from O2 appear to consist mostly of alpha-Fe2O3.
Superparamagnetic metallic Fe dominates in a protected system. The mat
erials were characterized by the Faraday magnetostatic method and Moss
bauer spectroscopy. Some hypotheses relating to the genesis of the mat
erials are suggested.
