nanocubes with high magnetization were prepared by a hydrothermal method. The structural, optical, morphology, and magnetic properties were investigated. The as-prepared sample exhibited a uniform cubic morphology with a high-saturation magnetization of 94.6 emu/g, therefore, can be easily collected from an aqueous solution using a magnet.
