摘要:

基于对实验矫顽力特性的批判性分析,回顾了RFEB磁体中反转机制的一般考虑。通过绘制在各种磁体中获得的实验参数,证明了反转过程的共同特征。建模提供了一个几乎定量的描述,在这些材料的结晶性,并允许连接的缺陷特性的反转机制。

英文摘要:

Based on a critical analysis of the experimental coercive properties, general considerations on the reversal mechanisms in RFeB magnets are recalled. By plotting together the experimental parameters obtained in various magnets, common features of the reversal processes are demonstrated. Modeling provides an almost quantitative description of coercivity in these materials and permits connecting the defect characteristic properties to reversal mechanisms.
