Barium hexaferrites (BaFe₁₂O₁₉) nanoparticles are prepared using γ-ray irradiation assisted polyacrylamide gel method (RIAPGM). The experiment parameters of as-prepared samples are investigated in detail, such as polymerization initiation mode and annealing temperature. The thermal decomposition behavior of BaFe₁₂O₁₉ xerogels were measured by thermogravimetric and differential scanning calorimetry (TG–DSC). The structure, optical, magnetic and electrochemical properties of BaFe₁₂O₁₉ nanoparticles were examined by various characterization techniques. The optical and magnetic properties of BaFe₁₂O₁₉ nanoparticles are emphatically researched by changing the annealing temperature. The BaFe₁₂O₁₉ nanoparticles prepared by RIAPGM exhibits uniform particle size distribution, excellent magnetic and electrochemical properties due to the effect of facet-dependent behaviour.
