摘要：

This paper demonstrates the possibility of the preparation of Fe3O4/BaTiO3 core-shell composites. BaTiO3-coated Fe3O4 (Fe3O4/BaTiO3) with 5-15 nm Fe3O4 nanoparticles as cores and 2.5-4 nm BaTiO3 shell thickness, was successfully prepared through coprecipitation method and sol-gel deposition technique. High-Resolution Transmission Electron Microscopy (HRTEM), Energy Dispersive X-ray Spectrometry (EDXS) and Selected-Area Electron Diffraction (SAED) showed the formation of the core-shell structure with face centered cubic Fe3O4 and tetragonal BaTiO3 phases.
