Magnetic and magneto-optical properties of the Co-γFe2O3 perpendicular magnetic films

Abstract
Co‐γFe2O3 films have been prepared by annealing Fe3O4/CoO multilayers. The crystalline orientation of multilayers change with bilayer thickness Λ; the [100] axis of Fe3O4 and CoO orients perpendicular to the film plane for Λ2O3 films obtained from multilayers of Λ2O4.
