摘要
本文用穆斯堡尔效应和X射线衍射等方法对不同添加物的SrFe_(12)^-O_(19)铁氧体永磁材料进行了研究。结果表明,可以观察到材料中的不同添加物与铁原子核的超精细相互作用的差异,以及它们对磁性能的不同影响。加入适量的SrSO_4和H_3BO_3作为添加物,有利于磁性能的改善。
The permanent-magnet materials of SrFe_(12)O_(19) ferrite containing various additions have been investigated by Mossbauer effect and X-ray diffraction method, We have observed the difference in the hyperfine interaction of various impurities to iron nuclei and the influence various impurities over the magnetic properties of the materials. The suitable addition of SrSO_4 and H_3BO_3 can improve the magnetic properties of SrFe_(12)O_(19) ferrite.
