The causes of reversible variation of coercivity in alloys for permanent magnets as a result of cyclic heat treatments are analyzed including the effect of magnetostatic interaction between microvolumes on the processes of magnetization reversal and on the magnitude of the reversibility of the coercivity. A scheme of the processes occurring in alloys of the Sm – Co – Cu – Fe – Zr system is suggested, which makes it possible to explain logically the mechanism of the “damage – restoration” phenomenon.

Sm（Co，Fe，Cu，Zr）7.5合金“损伤-修复”处理下矫顽力的可逆变化机理

分析了由于循环热处理而导致的永磁体合金中矫顽力可逆变化的原因，包括微小体积之间的静磁相互作用对磁化反转过程和矫顽力可逆性大小的影响。提出了一种在Sm-Co-Cu-Fe-Zr系统合金中发生的过程的方案，这使从逻辑上解释“损伤-还原”现象的机理成为可能。
