Preparation and Magnetic Properties of BiFeO3 and NiCuZn Ferrite Multiferroic Composites

摘要：

　　A series of xBiFeO3-(1-x) NiCuZn ferrite multiferroic composites have been prepared by solid state reaction method,in which x is 0.1,0.3,0.5,0.7,0.9 and 1.0.Composites are densified at 700 ℃ for 3 h.XRD results show that ferroelectric phase and ferromagnetic phase can be co-existed in the composites.The density of composites increases with an increase of BiFeO3 content.SEM results reveal that the bigger grains are BiFeO3 and the smaller grains are NiCuZn ferrite.Composites exhibits the typical magnetic hysteresis loops.Increasing x,the saturation magnetization of composites linearly decrease.The real part of permeability for composites decreases with increasing x.Meanwhile,the peak of imaginary part of permeability shifts toward higher frequency.
