摘要:<正> Rare earth cobalt permanent magnetic alloys are a new

generations of permanent magnets developed in the last decade, of

which SmCo_5 permanent magnets are the best developed and have so

far been the most widely used Re-Tin material. Its magnetization

reversal mechanism is nucleation. The magnetization reversal

undergoes several proceases such as nucleation, growing,

detaching and pinning at grain boundaries, etc. For sintered

magnet, in order to attain high coercive force, not only high

nuclea-
