摘要

多篇论文报道了单晶正铁氧体 DyFeO3 样品的实验现象：在沿样品易磁化方向的恒定低磁场下，样品磁化率随温度升高而增加，然后达到最大值。利用低温时的磁畴壁钉扎和高温时的磁畴壁脱钉现象可以更好地解释这些现象，而之前的论文忽略了这一点。在本文中，我们认为必须考虑磁畴壁运动才能解释这些实验现象。基于 O 2p 流动电子模型，我们讨论了磁畴的作用以及相关单晶材料中阳离子磁矩的特征。

Magnetic domain wall pinning and depinning in DyFeO3 single crystal

Several papers reported the experimental phenomena of single crystal orthoferrite DyFeO3 samples: the sample magnetization increases with increasing temperature, under a constant low magnetic field along the easy magnetizing direction of the samples, and then reaches a maximum value. These phenomena are better explained using magnetic domain wall pinning at low temperatures and depinning at high temperatures, which were neglected in previous papers. In this article, we argue that the magnetic domain wall motion must be taken into consideration in order to explain these experimental phenomena. Based on an O 2p itinerant electron model, we discussed the role of the magnetic domain and the characteristics of cation magnetic moments in relevant single crystal materials.
