摘要

Magnetic nanoparticles of cobalt ferrite have been synthesized at different temperatures without any subsequent heat treatment. The particle size, crystal structure and magnetic properties of as-synthesized particles were investigated by X-ray diffraction, transmission electron microscopy, scanning electron microscopy, Raman spectroscopy and vibrating sample magnetometer. The nanoparticles are of cubic spinel structure and equiaxial shape. The average size of nanoparticles increases with the increase of reaction temperature. Magnetic properties of nanoparticles show strong dependence on the particle size. A maximum coercivity of 3267 Oe and a maximum remanence ratio of 0.58 are obtained from the sample synthesized at 80 °C.
