Abstract

BaTiO ₃- Ni _xZn _1-xFe ₂O ₄ core-shell particles were prepared by plating Ni _xZn _1-xFe ₂O ₄ magnetic films on BaTiO ₃ via homogeneous coprecipitation with urea as the precipitator. The phase structure, morphology, particle size, shell thickness, chemical composition and magnetic performance of the core-shell particles were characterized by X-ray diffraction(XRD), transmission electron microscopy(TEM), energy dispersive X-ray spectroscopy(EDS) and vibrating sample magnetometer(VSM), respectively. The results show that compact and continuous coatings of Ni _xZn _1-xFe ₂O ₄ are formed on the surface of the BaTiO ₃. The magnetic performance of BaTiO ₃- Ni _xZn _1-xFe ₂O ₄ core-shell particles could be controlled via regulating the molar ratio of NiCl ₂·6H ₂O to ZnCl ₂ added in the experiment. When the molar ratio of NiCl ₂·6H ₂O to ZnCl ₂ is 7:3, the saturation magnetization(M _s) and the coercivity(H _c) of the as-sample are 26.999 A·m ²/kg and 902.787 A/m, respectively.
