为研究稀土掺杂W型铁氧体材料的吸波性能,实验用溶胶-凝胶法制备了W型铁氧体BaCoZnRe0.1Fe15.9O27(Re=Ce、La、Nd),研究了Re3+掺杂对W型铁氧体性能的影响.采用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、振动样品磁强计(VSM)和矢量网络分析仪等分析其物相组成、形貌、磁性能和微波吸收性能.结果表明:制得的Re3+掺杂W型铁氧体为六角片状结构,呈顺磁性;当样品BaCoZnFe16O27中掺杂Re3离子后,样品的晶粒尺寸变小,ε'减小,ε”增加,磁性能增强;BaCoZnNd0.1Fe15.9O27样品的饱和磁化强度(Ms)值最大,其tanδ在10.1 GHz处达到最大值0.58,吸波性能在2～ 13 GHz内最好.
