摘要
综述了高温永磁体的现状,总结了影响高温磁体使用温度的关键因素,介绍了永磁体Sm(CoCuFeZr)_z的发展状况,分析了成分对高温永磁体Sm(CoCuFeZr)_z使用温度(内禀矫顽力H_(ci)和温度系数β)的影响,概括了其矫顽力机理,并探讨了其今后的研究方向。
The present situation and the key factors of applied temperature are summarized on high temperature permanent magnets. The development status is introduced and the effect of component on applied temperature is analyzed on Sm(Co,Cu, Fe, Zr)_z permanent magnets, then the mechanism of coercivity is generalized. At last the research situation on Sm(Co, Cu, Fe, Zr)_z permanent magnets is discussed.
