<p> SiO<sub>2</sub>CuFe<sub>2</sub>O<sub>4</sub> nanoparticles encapsulated by different amounts of amorphous SiO<sub>2</sub> were prepared by a wet chemical method. These nanoparticles were characterized by X-ray diffraction and X-ray absorption fine structure analysis and found to have either a tetragonal or a cubic structure depending on the amount of SiO<sub>2</sub>. Magnetization measurements were performed for all samples using a SQUID magnetometer. The tetragonal nanoparticles showed a smaller maximum magnetization (<i>M</i><sub>S</sub>) and a larger coercive force (<i>H</i><sub>C</sub>) than the cubic nanoparticles.</p>
