摘要:采用高溫固相法制备了Sr1-xSmxFe12-xMnxO19(x=0~0.4)。利用XRD、SEM、VSM等表征手段对锶铁氧体的晶相、形貌和磁性能进行了表征。通过XRD分析发现当掺杂量0≤x<0.2时衍射峰基本没有出现杂峰,衍射峰的强度比较高,粉体为结晶度比较高的单一六方相锶铁氧体。通过SEM发现随着掺杂量的增加晶体的晶粒尺寸逐渐增大;通过VSM分析发现:随着掺杂量的增大矫顽力Hc出现先增大后减小的趋势。测试结果表明:当掺杂量在x=0.2时SmMn联合取代锶铁氧体的结晶度最好,矫顽力最大Hc=33.417emu/g。

Abstract:The Sr1-xSmxFe12-xMnxO19(x=0~0.4) materials were prepared by highheating solidstate reaction. The products were characterized by Xray diffraction (XRD), scanning electric microscope(SEM) and vibrating sample magnetometer(VSM). The XRD results analysis showed that Sm3+ and Mn2+ have been completely doped into strontium ferrite phase for Sr1-xSmxFe12-xMnxO19(0≤x<0.2). With the increase of SmMn content,the grain size gradually increases. VSM results indicate that the Hc increases (x being in the range of 0-0.2), and then decrease with the dosages of SmMn from 0 to 0.4. The results showed that when x being equal to 0.2, the crystallization was best and the maximum Hc (33.417emu/g) was obtained.
