摘要 本文讨论了永磁材料在温度老化处理前后磁性参量的稳定性、剩磁的不可逆损失、可逆损失的变化情况,同时探讨了采用老化处理及元素替代法对材料的温度系数的影响和某温区a_(Dr≈0的问题. The stability of Nd-Fe-B magnetic material , such as the irreversible loss,the reversible Ioss and ageing process is discussed.It is possible for the temporature coefficient of remanence to be Zero in some temperature range.
