N2 - The synthesis and characterization of composition (Ba,Sr)O.6Fe2(1-x)(Mn,Ti)xO3 (x = 0; 0.25; and 0.5) compound by using solid state reaction have been performed. The raw materials were BaCO3, 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 hour and furnace cooling. X-ray diffraction studies indicate expansion of hexagonal unit cell and compression of atomic density with substitution of Mn 2+ and Ti 4+ ions. The substitution increases density and intergrain connectivity in the microstructure of sintered samples. Effect of substitution upon magnetic properties revealed that total magnetization, remanence and coercivity changed with substitution due to preferential site occupancy of substituted Mn 2+ and Ti 4+ ions. Since the coercivity and total magnetization may be controlled by substitution while
