M-type Barium Hexaferrite Nanoparticles Synthesized by γ-Ray Irradiation Assisted Polyacrylamide Gel Method and Its Optical, Magnetic and Supercapacitive Performances

Barium hexaferrites (BaFe12O19) nanoparticles are prepared using gamma-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.
