In this paper, barrium hexaferrite nanoparticles have been successfully synthesized via sol–gel auto combustion method based on the reaction between Ba(NO 3 ) 2 and Fe(NO 3 ) 3 in water, in present of maleic acid as capping agent and fuel. Also, various polymers used to obtaining pure phase barrium hexaferrite. The products were characterized by X-ray diffraction, scanning electron microscopy, X-ray energy dispersive spectroscopy analysis. To investigate the effects of amount of maleic acid and the kind of polymer on the morphology of products and finding optimal condition, several experiments were carried out. It was found that the phase and morphology of products could be influenced by these parameters. Vibrating sample magnetometer (VSM) was used to study the magnetism properties of BaFe 12 O 19 samples.
