摘要:
 采用高温固相法制备了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Sm-Mn 联合取代锶
铁氧体的结晶度最好,矫顽力最大Hc = 33. 417 emu /g。
Abstract:
 The Sr1 - x SmxFe12 - x MnxO19
( x = 0 ~ 0. 4 ) materials were prepared by high-heating solid-state
reaction. The products were characterized by X-ray 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 Sm-Mn
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 Sm-Mn 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. 417 emu /g) was obtained.
