  In this paper, cobalt ferrite nanoparticles were synthesized using a co-precipitation method. The properties and characteristics of the cobalt ferrite nanoparticles were studied using XRD, VSM, and FESEM analyses. The FESEM images showed that the cobalt ferrite nanoparticles had almost spherical morphology, and that the particle size distribution (determined with the help of Digimizer software) was in the range of 25–60 nm. Moreover, the average size of the nanoparticles was calculated to be in the range of 37-47 nm. The VSM results indicated superparamagnetic properties of the cobalt ferrite nanoparticles at room temperature. Besides, the saturation magnetization and coercivity were found to be 30 emu/g and 39 Oe, respectively. The specific loss power (SLP) was investigated by preparing ferrofluid concentrations of 3, 5, and 8 mg/ml under a magnetic field of 400 Oe and at a frequency of 400 kHz. In this case, the rate of the increase in temperature of the cobalt ferrite nanoparticles was measured in a certain period of time, and the related SLP was calculated. The results of the measurements showed that the highest rate of the heat generation occured at the concentration of 8 mg/ml, leading to an SLP value of 162 W/g. Manuscript profile
