In this research, barium hexaferrite samples with BaZn0.6Zr0.3X0.3Fe10.8O19 (X=Ti,Ce,Sn) composition were synthesized via mechanical activation method and were evaluated by simultaneous thermal analysis (STA), X-ray diffraction (XRD), field emission electron microscopy (FE-SEM) and vibrating sample magnetometer (VSM). All of the synthesized samples were almost single phase and with average particles size of about 450 nm and 250 nm for samples without and with dopant respectively. Significant change in magnetic properties of barium hexaferrite were observed with effect of substitution of Fe ions. According to the results maximum magnetic saturation (33.1 emu/g) and minimum coercivity force (8.14 Oe) were related to samples with composition of BaZn0.6Zr0.3Ti0.3Fe10.8O19 and BaZn0.6Zr0.3Sn0.3Fe10.8O19 respectively.
