The Moessbauer study of 57Fe enriched α-Fe2O3 fine particles with and without adsorbed cobalt
Description
The coercivity Hc of γ-Fe2O3 and α-Fe2O3 particles increases with increasing content of adsorbed Co, until Hc reaches its maximum value. The Moessbauer spectra of 57Fe enriched α-Fe2O3 fine particles with and without adsorbed cobalt were measured. The change in the anisotropy constant from the Moessbauer spectra can interpret these coercivity changes. (orig.)
