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_(1.98)RE_(0.02)O_4(RE=Pr, Nd, Sm)纳米丝。利用X射线衍射仪(XRD)、傅里叶变换红外光谱仪(FT-IR)、扫描电子显微镜(SEM)和振动样品磁强计(VSM)对NiFe_(1.98)RE_(0.02)O_4(RE=Pr, Nd, Sm)纳米丝的结构、形貌和磁性能进行表征。结果表明,NiFe_(1.98)RE_(0.02)O_4(RE=Pr, Nd, Sm)纳米丝表面光滑、直径均匀、连续,直径约60 nm。掺杂Pr~(3+),Nd~(3+),Sm~(3+)均没有改变NiFe_2O_4的尖晶石结构,掺杂均降低了NiFe_2O_4的结晶度,晶粒尺寸D从44.8 nm减小到33.8 nm。NiFe_(1.98)RE_(0.02)O_4(RE=Pr, Nd, Sm)纳米丝都表现出软磁特性。NiFe_(1.98)RE_(0.02)O_4(RE=Pr, Nd, Sm)纳米丝的饱和磁化强度(Ms)分别为39.58,41.10,34.23 A·m~2/kg;矫顽力(Hc)分别为14119.2,13678.4,15937.6 A/m;其中NiFe_(1.98)Nd_(0.02)O_4纳米丝的Ms(41.10 A·m~2/kg)最大,矫顽力Hc (13678.4 A/m)最小,软磁性能最好。
