Magnetic CoFe2O4 nanoparticles were synthesized via a simple chemical reaction using precipitation method. The obtained materials consist of ferrite particles with average diameter of 25 nm. The effect of different surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. Scanning electron microscopy was used to study the structure and particle size of CoFe2O4 nanoparticles. Magnetic properties of the product were also examined by vibrating sample magnetometer at room temperature. By using ammonia and sodium hydroxide cobalt ferrite nanoparticles exhibit different super-paramagnetic and ferrimagnetic behaviors respectively.
