The nanoparticles were characterized by X-ray diffraction, transmission electron microscopy, vibrating sample magnetometer, and laser scattering particle size distribution analysis. Average size of the nanoparticles was about 32 nm with a narrow size distribution. Melting point of the nanoparticles was about 451.3℃.
