Synthesis and Characterization of Magnetic γ-Fe₂O₃/Al₂O₃ Core-Shell Nanocomposites

Article Preview

Abstract:

The γ-Fe₂O₃/Al₂O₃ core-shell nanocomposites (MCSs) were successfully synthesized by using heterogeneous nucleation method. The results show that a core-shell structures exit in γ-Fe₂O₃/Al₂O₃ MCSs and that the size of γ-Fe₂O₃/Al₂O₃ MCSs is in nanoscale. The saturated magnetization and coercivity of γ-Fe₂O₃/Al₂O₃ MCSs decrease compared with that of γ-Fe₂O₃ nanoparticles. However, the infrared absorbing ability of γ-Fe₂O₃/Al₂O₃ MCSs is obvious enhanced and it is expected to become a new series of absorbing materials applied in military field.
