Abstract
The γ-Fe2O3 powder with CoxFe3-xO4-doped coating was obtained by reaction of the γ-Fe2O3 powder in the solutions containing Co++ and Fe++ ions. It was found that this epitaxial CoxFe3-xO4 coating raised the coercivity of the γ-Fe2O3 from 420 (Oe) to 715 (Oe).The epitaxial CoxFe3-xO4 coating was isvestigated by means of M?ssbauer Effect of 57Fe. The M?ssbauer Spectrum indicates that the surface of γ-Fe2O3 was doped with CoxFe3-xO4 solid solution, and a static magnetic interaction takes place between the γ-Fe2O3 matrix and CoxFe3-xO4 solid solution.
