The samples were characterized to identify the physical properties. XRD pattern of cobalt ferrite samples showed the structure of body center cubic (bcc) structure. The diameter of as-prepared samples was determined about 20 nm and annealed one was about 30 and 50 nm in diameter at 500 °C and 1100 °C, respectively. The TEM studies showed that the particles change from rod shaped to sphere-liked shaped particles by increasing annealing temperature. Peaks in the FTIRspectrum determined the element of Fe-Co nanoparticles. EDS shows peaks of iron and cobalt with fewer impurities in prepared samples and Fe/Co ratio was also decreased with increasing annealing temperature. The result of magnetic measurements showed saturation magnetization around 59.5 emu g-1 for annealed samples.
