摘　　要：自旋系统是一类基于电子自旋工作的器件,具有高速、低功耗等优点,其中磁存储器被认为是下一代存储器的领跑者之一。二维材料有着天然的界面性能优势,接近微缩极限的尺寸特点,以及二维结构带来的物理特性,在自旋系统中有望得到广泛运用。本文概述了二维材料在自旋领域的最新研究进展,介绍了一些常见的二维磁性材料,讨论了基于二维材料的二维自旋器件,以及回顾了基于二维材料的磁性调控,最后总结了这一领域仍然面临的挑战,并对未来发展进行了展望。pintronic systems,where spin replaces charge,are known for their high speed and low power consumption.Magnetic random access memory(MRAM),a typical spintronic system,is seen as one of the best candidates of next-generation memory devices.In the field of Spintronics,two-dimensional(2D)materials are of increasing attention due to the high-quality surfaces,the scales approaching the scaling limit and the unique physical properties induced by their 2D structure.In this article,we outline the recent advances in spintronic systems based on 2D materials.First,we introduce some 2D magnetic materials and their common properties.Next,we discuss several main spintronic devices and representative works.Then we come to the modulation of magnetism based on 2D materials.Finally,we provide a brief summary of the whole article and an outlook for future development.
