Co0.5Ni0.5Fe2O4 nanoparticles have been synthesized by a stearic acid method. Core/shell Co0.5Ni0.5Fe2O4/SiO2 nanomaterials at varying amount of SiO2 are prepared by hydrolysis and condensation of tetraethyl orthosilicate (TEOS) precursor. The composition phase and average crystallite size have been...
