Abstract

Thermal fluctuations in two-dimensional (2D) isotropy systems at non-zero finite temperatures can destroy the long-range (LR) magnetic order due to the mechanisms addressed in the Mermin-Wanger theory. However, the magnetic anisotropy related to spin-orbit coupling (SOC) may stabilize magnetic order in 2D systems. Very recently, 2D FeGeTe (3 ≤ ≤ 7) with a high Curie temperature () has not only undergone significant developments in terms of synthetic methods and the control of ferromagnetism (FM), but is also being actively explored for applications in various devices. In this review, we introduce six experimental methods, ten ferromagnetic modulation strategies, and four spintronic devices for 2D FeGeTe materials. In summary, we outline the challenges and potential research directions in this field.

摘要

在非零有限温度下，二维（2D）各向同性系统中的热涨落会由于Mermin-Wanger理论中所阐述的机制破坏长程（LR）磁序。然而，与自旋轨道耦合（SOC）相关的磁各向异性可能会使二维系统中的磁序稳定下来。最近，具有高居里温度（）的二维FeGeTe（3≤≤7）不仅在合成方法和铁磁性（FM）控制方面取得了重大进展，而且正在被积极探索用于各种器件。在这篇综述中，我们介绍了二维FeGeTe材料的六种实验方法、十种铁磁调制策略和四种自旋电子器件。总之，我们概述了该领域的挑战和潜在研究方向。
