Abstract
The doped barium hexaferrite, BaFe12−x(Mg0.5Ti0.5)xO19 with 1≤x≤5, is synthesized by a solid state ceramic method. Its crystalline structure, morphology, as well as static and dynamic magnetic properties are investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), vibrating sample magnetometry, and vector network analysis, respectively. The cation distribution of Mg2+ and Ti4+ in the hexagonal structure of BaFe12−x(Mg0.5Ti0.5)xO19 is investigated by 57Fe Mössbauer spectroscopy. The effect of Mg2+ and Ti4+ dopants on static and high-frequency magnetic properties of the ferrite is studied.
