摘　　要：利用静电纺丝法制备了CoFe2-xCexO4纳米带(x=0, 0.03, 0.07),并使用扫描电子显微镜(SEM),透射电子显微镜(TEM),X-射线衍射仪(XRD)与振动样品磁强计(VSM)来表征样品的形貌、结构与磁性能。结果表明,随着稀土元素Ce的掺入,样品的晶粒尺寸与饱和磁化强度以及矫顽力逐渐减小。CoFe2-xCexO4 nanobelts(x = 0, 0.03, 0.07) were successfully prepared by using electrospinning technique. The morphology, crystal structure and magnetic properties of the samples were characterized and tested by using transmission electron microscope, scanning electron microscope, X-ray diffractometer and vibrating sample magnetometer. The results showed that the grain size of crystallites, the saturation magnetization and the coercivity force of samples decreased with the incorporation of earth element Ce.
