摘　　要：本文针对毫米波高功率环行器对微波铁氧体材料的技术要求,开展了高功率NiZn铁氧体材料的研究工作。在理论分析的基础上,固化制备工艺参数,通过配方Zn^(2+)、Co^(2+)掺杂,得到饱和磁化强度和自旋波线宽的变化规律,最终研制出饱和磁化强度到达4008Gs、自旋波线宽达到28.3Oe的毫米波高功率铁氧体材料,满足了器件使用需求。According to the technical requirements of a millimeter-wave high-power circulator on microwave ferrite materials,the research on a high-power NiZn ferrite material is carried out in this paper.On the basis of theoretical analysis,the preparation technique parameters are determined.Through the doping of Zn^(2+)and Co^(2+),the variation rules of saturation magnetization and spin wave linewith are obtained.Finally,a millimeter-wave high-power ferrite material with a saturation magnetization up to 4008Gs and a spin wave linewidth up to 28.3Oe is developed,which meets the requirements of the target device.
