| Abstract | 采用溶胶-凝胶法、静电纺丝技术和热处理技术相结合制备了一维NiFe_(2 - x)Sm_xO_4 (x = 0,0.02,0.04,0.06,0.08,0.1)纳米丝。利用X射线衍射仪(XRD) 、傅立叶变换红外光谱仪(FT-IR) 、扫描电子显微镜(SEM)和振动样品磁强计(VSM)对NiFe_(2 - x) Sm_xO_4纳米丝的结构、形貌和磁性能进行表征。结果表明: NiFe_(2 - x)Sm_xO_4纳米丝表面光滑、直径均匀、连续,直径约60 nm。掺杂Sm~(3 +)没有改变NiFe2O4的尖晶石结构,随着Sm~(3 +)掺杂量的增大,晶粒尺寸D从44.8 nm减小到19.6 nm。NiFe_(2 - x) Sm_xO_4纳米丝表现出软磁特性。随着Sm~(3 +)掺杂量的增大, NiFe_(2 - x)Sm_xO_4纳米丝的饱和磁化强度(Ms) 、剩余磁化强度(Mr)和矫顽力(Hc)先减小后增大,在x = 0.08时分别达到最小值22.54,2.98 emu·g ~(- 1) ,90.33 Oe。 |
