Abstract
In the present study, we have investigated the influence of different types of doping elements on magnetic properties of M-type BaFe12O19 samples. It was observed that Nb2O5 addition increases the coercive field, the remanence magnetization (M r), and saturation magnetization (M s) values by about 27 %, 47 %, and 53 %, respectively. In the same manner, MnO2 also improves the magnetic parameters significantly. The M r and M s values show increments up to 40 % in magnitude. On the other hand, the best magnetic properties were achieved by the addition of CuO to the B2O3 doped BaFe12O19. These materials have M r and M s values up to ∼34 emu/g and ∼62 emu/g, respectively.
