Soft magnetic FeNi-X (X= CuO, NiO, and CoO) exchange coupled nanocomposites prepared via ball milling
Exchange coupled magnetic nanocomposite powders were obtained by mechanically milling ferromagnetic (FM)-antiferromagnetic (AFM) powders. A shift in the field cooled (FC) hysteresis loop and the coercivity (Hc) enhancement of the FM phase resulting from exchange bias anisotropy was observed. A model based on Preisach hysteresis model was used to calculate the interfacial energy between FM and AFM particles. The calculated interfacial energies were in good agreement with those reported for polycrystalline AFM thin films.
