Abstract The migration process of Co ions in the cobalt-ferrite epitaxial layer on γ-Fe₂O₃ powder has been studied by magnetic thermal annealing method. The activation energy E and coefficient A of Co ions have been measured. An abnormal increase of coercivity of sample annealed in a transverse magnetic field was found. On the basis of Mössbauer and XPS results the reason of this phenomenon is discussed.
