Nanoparticles possess unique properties, which can be applied in medical applications; they address targets such as cellular therapy, tissue repair, Nano-biosensors, drug delivery, magnetic resonance imaging and magnetic fluid hyperthermia. In this work, different sized cobalt ferrite nanoparticles (CFNP) were synthesized with narrow size distribution, by using chemical precipitation methods, to aim for finding the optimum particle size which has high heating efficiency in the applied magnetic field. The obtained powder was calcined at different temperature (600°C, 800°C, 900°C, and 1000°C). The sample which characterized by Transmission Electron Microscopy (TEM) confirmed the formation of single-phase CFNP in the range 10–115 nm depending on the annealing temperature and Vibrating Sample Magnetometer (VSM) to get the magnetization and coercivity of the powder.
