Abstract:
Zn0.2Fe2.8O4 particles were prepared and coated with different amounts of cobalt-ferrite. The coercivity increases with increasing cobalt-ferrite coating. In the low Co-ferrite coating regime, the increase is induced by an enhanced anisotropy of the interface layer, while in the high coating regime, it is due to the Co-ferrite surface layer. The full depth of the interface layer was found to be approximately 8 Å, and the temperature dependence of the change in coercivity in both low and high Co-ferrite coating regimes was discussed. Mechanisms leading to a greatly increased coercivity of acicular Co-γ-Fe2O3 were also discussed.
