Abstract :
Details of fabrication and characterization of sol-gel produced CoFe2O4 nanoparticles embedded in the amorphous SiO2 matrix are presented with results of an extended magnetization study of these materials. Characterization is performed by powder X-ray diffraction and high resolution transmission electron microscopy.
