采用共沉淀法将Nd3+取代的Fe3O4与纳米石墨微片(NanoG)复合得到复合物NdxFe3-xO4/NanoG.通过SEM、LPSA、EDS、XRD和FTIR等对该复合物的结构进行了表征.当x=0.06时,Nd0.06Fe2.94O4具有尖晶石结构,其粒径主要分布在70～80 nm间.VSM的测试表明:Nd0.06Fe2.94O4为软磁性铁氧体,具有较高的饱和磁化强度(Ms =43.74 emu/g),与NanoG复合后,饱和磁化强度下降到39.45 emu/g.对电磁参数的测试表明:当x=0.06,Nd0.06Fe2.94O4与NanoG的质量比为4∶1时,在X波段(8.2～12.4 GHz),Nd0.06Fe2.94O4/NanoG在11.90 GHz处的最小损耗为Rmin=-17.13 dB,具有较好的微波吸收性能.
