本文研究了表面活性剂辅助高能球磨法制备SmCo6.6Nb0.4纳米片的磁硬化机理。研究了热退磁后SmCo6.6Nb0.4纳米片的初始磁化曲线和相应的微分磁化率曲线的磁滞回线。结果表明，样品的磁化反转过程是由畴壁运动决定的，磁粉的磁硬化机制以畴壁钉扎为主。此外，纳米片的矫顽场对来自次要磁滞回线的最大施加场的依赖性也证实了磁化反转中的钉扎效应。
In this paper, we studied the magnetic hardening mechanism of SmCo6.6Nb0.4 nanoflakes prepared by surfactant-assisted high energy ball milling. The hysteresis loop with the initial magnetization curve and the corresponding differential susceptibility curve of thermally demagnetized SmCo6.6Nb0.4 nanoflakes were studied. It is concluded that the magnetization reversal process of the specimen is determined by domain wall motion, i.e., the magnetic hardening mechanism of the magnetic powders is dominated by domain wall pinning. Moreover, the dependence of coercive field of the nanoflakes on the maximum applied field derived from minor hysteresis loops also confirms the pinning effect in the magnetization reversal.
