M. Gibertini, M. Koperski, A. F. Morpurgo, K. S. Novoselov

摘要:

2D材料家族日益壮大,极大地扩展了在二维中探索的可能现象的范围,以及人们可以创建的可能的范德华异质结构。这种2D材料目前涵盖了广泛的属性。直到最近,这个家庭一直缺少一个关键成员- 2D磁铁。在过去的两年里,随着各种原子级薄的磁性晶体的引入,情况发生了变化。在这里,我们将讨论2D材料和块状晶体中磁状态之间的差异,并概述最近探索的2D磁体。我们将重点,特别是在两个最研究系统的情况下-半导体CrI $_3$和金属Fe $_3$ GeTe $_2$ -并说明已观察到的物理现象。特别注意将给予的范围内的新颖的范德瓦尔斯异质结构,成为可能与二维磁铁的外观,在这个迅速扩大的领域提供新的观点。

英文摘要:

The family of 2D materials grows day by day, drastically expanding the scope of possible phenomena to be explored in two dimensions, as well as the possible van der Waals heterostructures that one can create. Such 2D materials currently cover a vast range of properties. Until recently, this family has been missing one crucial member - 2D magnets. The situation has changed over the last two years with the introduction of a variety of atomically-thin magnetic crystals. Here we will discuss the difference between magnetic states in 2D materials and in bulk crystals and present an overview of the 2D magnets that have been explored recently. We will focus, in particular, on the case of the two most studied systems - semiconducting CrI$_3$ and metallic Fe$_3$GeTe$_2$ - and illustrate the physical phenomena that have been observed. Special attention will be given to the range of novel van der Waals heterostructures that became possible with the appearance of 2D magnets, offering new perspectives in this rapidly expanding field.
