The existence of spontaneous magnetization in low dimensional magnetic systems has attracted intensive studies since the early 60s and research remains very active even now. Only recently, magnetic van der Waals (vdW) systems down to a few layers have been broadly discussed for their magnetic order ground states at finite temperature. The naturally inherited layered structure of the vdW magnetic systems possessing onsite magnetic anisotropy from band electrons can suppress the long‐range fluctuations. This provides an excellent vehicle to study the transition of magnetism to 2D limits both theoretically and experimentally. Here the current status of 2D vdW magnetic system and its potential applications are briefly summarized and discussed.

二维范德华磁系统的前景与机遇

自60年代初以来，低维磁系统中自发磁化的存在就引起了广泛的研究，即使到现在，研究仍非常活跃。直到最近，由于在有限温度下的磁阶基态，人们广泛讨论了直到几层的范德华磁（vdW）系统。vdW磁系统的自然继承的层状结构具有带电子的现场磁各向异性，可以抑制远距离波动​​。这为从理论上和实验上研究磁性向2D极限的过渡提供了一个极好的工具。在此简要概述和讨论2D vdW磁系统的当前状态及其潜在应用。
