Recently, we have demonstrated the successful synthesis of Fe x Co1−x /Co y Fe3−y O4 nanocomposites with various alkaline solutions by using surfactants-assisted-hydrothermal (SAH) process. In this article, the synthesis of Fe x Co1−x /CoyFe3−y O4 nanocomposites with their sizes varying between 20 nm and 2 μm was reported. X-ray powder diffraction (XRD) analyses showed that the surfactants, pH, precipitator, and temperature of the system play important roles in the nucleation and growth processes. The magnetic properties tested by vibrating sample magnetometer (VSM) at room temperature exhibit ferromagnetic behavior of the nanocomposites. These Fe x Co1−x /Co y Fe3−y O4 nanocomposites may have a potential application as magnetic carriers for drug targeting because of their excellent soft-magnetic properties.
