Magnetic Properties and Structural Characteristics of BaFe12O19 Hexaferrites Synthesized by the Zol-Gel Combustion

The phase structure, structural parameters, and basic magnetic characteristics of BaFe₁₂O₁₉ hexaferrites prepared by the zol-gel combustion method with subsequent annealing at a temperature of 850°С for 6 h are investigated. The influence of the organic fuel type on the properties of synthesized materials is analyzed. Values of the saturation magnetization and the anisotropy field are determined. It is established that they depend on the organic fuel type. It is shown that powders synthesized with citric acid used as a fuel have the largest particle sizes and the highest saturation magnetization.
