In this work, BaFe12-2xCuxTixO19 (x=0, 0.05, 0.10, 0.15 and 0.20) ferrites were fabricated at the optimum temperature of 1200 oC from BaCO3, Fe2O3, CuO and TiO2 powders by using a conventional solid-state-reaction sintering method. The co-doping effect of Cu2+-Ti4+ on the microstructure and magnetic properties of the as-prepared ferrites was investigated. It was revealed that the doped Cu2+-Ti4+ could enter into the lattice of BaFe12O19, and no second phase was observed in the doped samples. The coericivity of the prepared samples decreased from 204.46 to 86.82 kA/m with increasing doping amount of Cu2+-Ti4+ ions. The saturation magnetization fluctuated somewhat between 54.61 and 58.42 A?m2/kg with increasing content of Cu2+-Ti4+ ions. With increasing doping amount of Cu-Ti ions, the dielectric constant increases first and then decreases, but the change in dielectric loss is very weak.
