通过化学共沉淀法制备了 NiCuZn 铁氧体纳米微粒，采用 X 射线衍射仪、透射电镜以及振动样品磁强计分析研究 Mg2+和 Co2+共同取代 Ni2+对铁氧体微观结构和饱和磁化强度的影响。结果表明，适量的Mg2+和Co2+取代Ni2+后，试样依然能够形成单一的尖晶石结构，没有第二相杂质出现；试样的晶格参数a 和平均粒径Dx 随Mg2+和 Co2+取代量的增加而增大；透射电镜图片显示试样中有少量多面体形状的颗粒，并且出现团聚现象；饱和磁化强度Ms 随Co2+取代量的增加单调增大，随Mg 2+取代量的增加先增大后减小，并且在Mg2+的取代量为0.05、Co2+的取代量为0.08时，试样具有最大饱和磁化强度。
In this paper,NiCuZn ferrite nanoparticles were prepared by chemical coprecipitation method.The effect of Mg2+ and Co2+ substitution on microstructure and magnetic properties were investigated.It was found that after appropriate content of Mg2+ and Co2+ replaced Ni2+,all the samples could still form single spinel structure.Lattice parameter and average grain size was found to increase with increasing Mg2+ and Co2+ con-tent.TEM images showed a small amount of polyhedron particles in samples,and all the samples were aggre-gated.Saturation magnetization was found to increase with increasing Co2+ content monotonously,and increase with Mg2+ substitution for Ni2+,up to x=0.05.When x=0.05,y=0.08,sample had the maximum satura-tion magnetization.
