采用固相法制备了SmCu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。
Sm-Cu substituted strontium ferritesSr1-xSmxFe12-xCux19(x=0.00-0.20) were prepared by the solid-statereaction X-raydiffraction (XRD)
scanning electron microscopy (SEM) and vibrating samplemagnetometer (VSM) were employed to analyze the phase structure
morphology andmagnetic performance
respectively The results show that the saturationmagnetization (Ms)
coercivity (Hc) and remanence magnetism (Mr) firstincreases and then decreases with increasing xWhen the doping amount x of Sm-Cuis 0.05
the Mr reaches a maximum value of 24.173emu/g. The doping amountx of Sm-Cu is 0.10
the Ms and Hc values turn to be the maximumvalues of 51.757emu/g and 809.904Oe
respectively.
