论文摘要
自从发现石墨烯以来，具有原子水平厚度的二维材料已迅速发展为具有跨学科利益的物理科学领域，因为它们的引人入胜的特性和广泛的应用。最近，在Cr $ _2 $ _2 $ _2 $ _6 $ _6 $ bilayer和cri $ _3 $单层中对铁磁性的实验性观察打开了一扇门，以二维材料中的长期含有内在的磁性订单。同时，在SNTE Monolayer和Cuinp $ _2 $ S $ _6 $几层中也发现了铁电性。这些铁阶在二维极限中的出现不仅为我们的物理知识带来了新的挑战，而且为潜在应用提供了更多功能。在各种二维铁井层材料中，过渡/稀土金属卤化物及其衍生物非常普遍。在此研究更新中，基于过渡/稀土金属卤化物，将说明各种铁阶在二维中的物理学。还将讨论基于其磁性和极性特性的潜在应用。
Since the discovery of graphene, two-dimensional materials with atomic level thickness have rapidly grown to be a prosperous field of physical science with interdisciplinary interests, for their fascinating properties and broad applications. Very recently, the experimental observation of ferromagnetism in Cr$_2$Ge$_2$Te$_6$ bilayer and CrI$_3$ monolayer opened a door to pursuit long-absent intrinsic magnetic orders in two-dimensional materials. Meanwhile, the ferroelectricity was also experimentally found in SnTe monolayer and CuInP$_2$S$_6$ few layers. The emergence of these ferroic orders in the two-dimensional limit not only brings new challenges to our physical knowledge, but also provides more functionalities for potential applications. Among various two-dimensional ferroic ordered materials, transition/rare-earth metal halides and their derivants are very common. In this Research Update, based on transition/rare-earth metal halides, the physics of various ferroic orders in two-dimensional will be illustrated. The potential applications based on their magnetic and polar properties will also be discussed.
