摘要(Abstract)：

以废旧锂离子电池为原料,柠檬酸为凝胶剂,通过溶胶-凝胶自蔓延燃烧法制备出镧掺杂钴铁氧体,用X射线衍射仪(XRD)、场发射扫描电镜(SEM)、透射电镜(TEM)、振动样品磁强计(VSM)和磁致伸缩性能自动测量仪分析所制备样品的晶型、形貌、磁性和磁致伸缩性.结果表明,镧掺杂的钴铁氧体具有尖晶石结构,性能较纯钴铁氧体有所改变,随着La元素掺杂量的增加,样品的饱和磁化强度,磁致伸缩系数,应变导数逐渐减小.当掺杂量x=0.025时,应变导数在较低的磁场下取得最大值-1.18×10-9 m/A,这有利于氧化铁系的磁致伸缩材料在非接触式传感器和执行器方面的应用.
Using spent Li-ion batteries as raw materials,critic acid as gelatin,a series of La-doped cobalt ferrite were synthesized by a sol-gel auto-combustion technique.The crystalline form,structural,magnetic and magnetostrictive properties of the samples were analyzed by X-ray diffraction(XRD),scanning election microscopy(SEM),transmission electron microscope(TEM),vibrating sample magnetometer(VSM),and magnetostrictive coefficient measuring system.Results showed that the La-doped cobalt ferrites had a spinel structure.The particle sizes were uniform,and the properties were changed compared with the pure cobalt ferrite.The saturation magnetization,magnetostriction coefficients,and strain derivative for each samples decreased with increasing La-doped content.When the doped content x was 0.025,the strain derivative reached a maximum value-1.18×10-9 m/A under a lower magnetic field which was advantageous for the application of the iron oxide-based magnetostrictive material in non-contact sensors and actuator.
