Nanocomposites from M-type hexaferrite BaFe nanoparticles according to the formula [(x)(Ba Fe 11. 7 11. 7 Al Al 0.15 0.15 Zn Zn 0.15 0.15 O O 19 19 and spinel ferrite Mn ) þ (1 e x)(Mn ); x ¼ 0.3, 0.4 and 0.5] have been manufactured by the citrate combustion method. The structure and morphology of the nanocomposites were appointed by X-ray diffraction (XRD) analysis and field emission scanning electron microscopy (FESEM). The remanent magnetization and coercivity of the nanocomposites became 2 and 2.5 times higher, respectively by adding BaFe 11. 7 Al 0.15 Zn 0.15 O 19 0.8 phase. The Cole-Cole plots of the nanocomposite x ¼ 0.4 at the selected temperatures shows two successive semicircles at all the selected temperatures. The first low frequencies semicircle elucidates the contribution of the grain boundary and the second one, at high frequencies, gives the contribution of grain to conduction process. Multilateral applications for exchange spring magnets can be manufactured using those nanocomposites. Mg 0.2 Fe 0.8 2 Mg O 4 0.2 Fe 2 O 4
