|Abstract:||Al-substituted Ba-ferrite in the form of BaFe10Al2O19 was prepared by mechanical alloying and subsequent heat treatment. Their structure and magnetic properties were investigated in comparison with Ba-ferrite without Al substitution. After annealing at 1100 °C, a coercivity as high as 9.3 kOe was measured, while the coercivity values of the Ba-ferrite samples without Al substitution with a similar particle size were observed in the range of 5-6 kOe. A significant reduction of saturation magnetization was observed as compared to pure barium ferrite.|
