The magnetic glass-ceramics was prepared by a melt-quenching method with the phase-separated melts in two-liquids stable immiscibility region of Fe 3O4-MnO2-SiO2 system. The obtained glass-ceramics had spinel single phase of Fe3O4-MnO 2 solid solution, and showed ferromagnetic properties. The saturated magnetization became a maximum by adding a small amount of MnO2 with low coercive force. These properties of both high magnetization and low coercive force by Mn doping are very effective to realize the magnetic materials for the hyperthermia treatment.
