Since the discovery of intrinsic ferromagnetism in atomically thin Cr₂Gr₂Te₆ and CrI₃ in 2017, research on two-dimensional (2D) magnetic materials has become a highlighted topic. Based on 2D magnetic materials and their heterostructures, exotic physical phenomena at the atomically thin limit have been discovered, such as the quantum anomalous Hall effect, magneto-electric multiferroics, and magnon valleytronics. Furthermore, magnetism in these ultrathin magnets can be effectively controlled by external perturbations, such as electric field, strain, doping, chemical functionalization, and stacking engineering. These attributes make 2D magnets ideal platforms for fundamental research and promising candidates for various spintronic applications. This review aims at providing an overview of the structures, properties, and external controls of 2D magnets, as well as the challenges and potential opportunities in this field.

二维磁性材料：结构，特性和外部控制

自从发现原子薄的Cr ₂ Gr ₂ Te ₆和CrI _3中的固有铁磁性以来在2017年，二维（2D）磁性材料的研究已成为热门话题。基于二维磁性材料及其异质结构，已经发现了原子稀薄极限处的奇异物理现象，例如量子反常霍尔效应，磁电多铁性和磁子谷电子。此外，这些超薄磁体中的磁性可以通过外部扰动（例如电场，应变，掺杂，化学功能化和堆叠工程）来有效控制。这些特性使2D磁体成为基础研究的理想平台，并且是各种自旋电子学应用的有希望的候选者。这篇综述旨在概述2D磁体的结构，性能和外部控制，以及该领域的挑战和潜在机会。
