Morphology and Magnetic Properties of NiCuZn Ferrite Synthesized by Solid-molten Salt Method

摘要：

　　Cu doped NiCuZn ferrite Ni0.4-xCuxZn0.6Fe2O4 (x=0.16~0.28) have been prepared by the solid-molten salt method using NaC1 as flux.The structure and properties were investigated by X-ray diffraction(XRD), scanning electron microscope (SEM) and vibrating sample magnetometer (VSM) techniques.It is found that addition of Cu2+ results in the particles size growing up because of the tend of crystal structure to be a normal Zn ferrite.The Ms values of NCZF are decrease gradually with increasing of Cu content.Curie temperature (Tc) increases with Cu2+ content in the range of x<0.20, and then decreasing rapidly.This can be ascribed to that the lower magnetization moment Cu2+ ion amount of B-site increasing leads to weaker super-exchange effect.
