On the Coercive Forces of the Powder-Sintered Nd₁₅Fe₇₇B₈PM Alloy

摘要

摘要: 通过测量粉末烧结Nd₁₅Fe₇₇B₈永磁合金的充磁和退磁曲线,结合金相组织及磁畴观察分析,证明该合金的矫顽力是由畴壁的钉扎来控制的。

Abstract: In this paper,the dependence of the coercive forces of the power-sintered PM alloy Nd₁₅Fe₇₇B₈ on the domain wall pegging has been justified through the determination of its hysteresis loop in combination with the observation on the alloy structures and its magnetic do-mains.
