摘要:
 采用固相法制备了SmCu联合取代的锶铁氧体Sr1-xSmxFe12-xCuxO19(x=0.00-0.20)。利用XRD、SEM及VSM对锶铁氧体的晶相组成、微观形貌及磁学性能进行了研究。结果表明:随着掺杂量x的增加饱和磁化强度Ms,矫顽力Hc以及剩磁Mr均出现先增大后减小的趋势;当Sm-Cu掺杂量x=0.05时,剩磁Mr达到最大值Mr=24.173emu/g;当掺杂量x=0.10时,饱和磁化强度达到最大值Ms=51.757emu/g,同时矫顽力也出现最大值Hc=809.904Oe。
Abstract:
 Sm-Cu substituted strontium ferrites Sr1-xSmxFe12-xCux19(x=0.00-0.20) were prepared by the solidstate reaction Xray diffraction (XRD), scanning electron microscopy (SEM) and vibrating sample magnetometer (VSM) were employed to analyze the phase structure, morphology and magnetic performance, respectively The results show that the saturation magnetization (Ms), coercivity (Hc) and remanence magnetism (Mr) first increases and then decreases with increasing xWhen the doping amount x of Sm-Cu is 0.05, the Mr reaches a maximum value of 24.173emu/g. The doping amount  x  of Sm-Cu is 0.10, the Ms and  Hc values turn to be the maximum values of 51.757emu/g and 809.904Oe, respectively.
