Abstract: The coexistence of ferromagnetic and ferroelectric properties in single phase material leads to the existence of new type of material known as magnetoelectric. In present work, magneto electric composites BaFe12O19 / BiFeO3 with different mass percentage of BiFeO3 (0, 25%, 50%, 75% and 100 %) were prepared. BaFe12O19 (BHF) and BiFeO3 (BiF) ferrites were prepared separately using Sol-gel auto combustion method and then physically mixed. Prepared composite samples were characterized using FTIR, XRD, SEM and VSM. XRD spectra reveal the mixed hexaferrite and bismuth ferrite phases. SEM micrograph of showed the formation of porous clusters of non uniform grains in the composites. Saturation magnetization of BaFe12O19 / BiFeO3 composites decreased gradually with increasing in BiFeO3 content and there is no systematic change in coercivity values.
Keywords: Magneto-electric, hexaferrite, multiferroic, VSM and composite.
