The synthesis and characterization of composition SrFe12-(x+y)MnxTiyO19 (x = y and x ≠ y) compound by using solid state reaction have been performed. The raw materials were SrCO3, Fe2O3, MnCO3, and TiO2. The mixed powder was compacted at 5000 psi into pellets and sintered at 1050°C in the air at atmosphere pressure for 15 hours and furnace cooling. The refinement results of x-ray diffraction pattern show that the doping composition (x = y) was a single phase while the doping composition (x ≠ y) was multi phase. We concluded that effect of substitution upon magnetic properties revealed that total magnetization, remanence and coercivity changed with substitution due to preferential site occupancy of substituted Mn2+ and Ti4+ ions. The coercivity decreases with increase in Mn and Ti concentration. This effect is related with Fe3+ magnetic moment changes after they have already substituted Mn2+ and Ti4+ ions. Since the coercivity and total magnetization may be controlled by substitution while maintaining resistive properties, making this material useful for microwave absorber.
