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