Microspheres with spinel Fe3O4 cores and anatase TiO2 shells are synthesized with different core sizes and shell thickneses. The as-synthesized microspheres have a unique morphology, uniform size, good crystallinity, favorable superparamagnetism, and high magnetization. The Fe3O4@TiO2 microspheres possess lower reflection loss and wider absorption frequency range than pure Fe3O4.
