Nanocrystalline cobalt ferrite (CoFe2O4) materials have been synthesized by citrate precursor and co-precipitation method. Samples are annealed at different temperatures to obtain the different nanocrystallite-size materials. All the samples crystallize to Fd3̅m space group in cubic symmetry. Magnetic hysteresis loops measurement has been carried out at room temperature using a vibrating sample magnetometer (VSM). The magnetic data in the saturation region have been analyzed by employing the law of approach (LA) to saturation technique. The anisotropy constant ( K1) is found to be higher in citrate precursor derived samples. The saturation magnetization ( Ms), coercivity ( Hc) , remanent magnetization ( Mr) and anisotropy constant ( K1) increases with the increase of crystallite size.
