 Abstract
 PDF
- Hexagonal barium ferrite (BaFe_12O_19) nano-particles have been successfully synthesised using selfassembly method. Diethyleneamine (DEA) surfactant was used to fabricate the micelle structure of Ba-DEA complex under various DEA concentrations. BaFe_12O_19 powders were synthesized with addition Fe ions to Ba-DEA complex and then heat treated at temperature range of 800-1000°C. The molar ratio of Ba/DEA and heat-treatment temperature significantly affected the magnetic properties and morphology of BaFe_12O_19 powders. BaFe_12O_19 powders synthesized with Ba/DEA molar ratio of 1 and heat-treated at 1000°C for 1 hour showed the coercive forces (iHc) of 4.84 kOe with average crystal size of about 200 nm.
