摘要

自从发现与其他退火方法相比,应力退火在非晶和纳米晶体合金中诱导了更大的各向异性以来,已经进行了大量的研究来解释这一现象。这导致了许多关于这种应力诱导的磁各向异性起源的建议,但到目前为止,这种起源是用两个相互竞争的模型来解释的:磁弹性效应模型和双原子对有序模型。尽管有这些理论,但由于缺乏对结构各向异性的直接观测,应力诱导各向异性的起源仍在讨论中。在本文中,我们回顾了一些用于讨论应力诱导磁各向异性起源的表征技术,以及迄今为止在统一所有被认为是FINEMET合金中应力诱导各向异性来源的对比观点方面所取得的进展。

Research Progress of Stress-Induced Magnetic Anisotropy in Fe-Based Amorphous and Nanocrystalline Alloys
Since it was discovered that stress annealing induced larger anisotropies compared to other annealing methods in amorphous and nanocrystalline alloys, there has been a lot of research done to explain this phenomenon. This has led to many suggestions about the origin of this stress-induced magnetic anisotropy, but till now the origin is explained with two competing models: the magnetoelastic effect model and the diatomic pair ordering model. In spite of these theories, the origin of the stress-induced anisotropy is still under discussion because direct observation of structural anisotropy is still lacking. In this paper, we have reviewed some of the characterization techniques which have been used to discuss the origin of stress-induced magnetic anisotropy and the progress which has been made thus far in unifying all the contrasting views which has been suggested to be the origin of the stress-induced anisotropy in FINEMET alloys.
