TLDR
Recognizing that magnetic anisotropy can be used to induce stable magnetism in atomic monolayers, Gong and Zhang provide an overview of the materials available and the physical understanding of the effects and then discuss how these effects could be exploited for widespread practical applications.Abstract:
Magnetism, originating from the moving charges and spin of elementary particles, has revolutionized important technologies such as data storage and biomedical imaging, and continues to bring forth new phenomena in emergent materials and reduced dimensions. The recently discovered two-dimensional (2D) magnetic van der Waals crystals provide ideal platforms for understanding 2D magnetism, the control of which has been fueling opportunities for atomically thin, flexible magneto-optic and magnetoelectric devices (such as magnetoresistive memories and spin field-effect transistors). The seamless integration of 2D magnets with dissimilar electronic and photonic materials opens up exciting possibilities for unprecedented properties and functionalities. We review the progress in this area and identify the possible directions for device applications, which may lead to advances in spintronics, sensors, and computing.read more

Yujun Deng,Yijun Yu,Yichen Song,Jingzhao Zhang,Naizhou Wang,Zeyuan Sun,Yangfan Yi,Yizheng Wu,Shiwei Wu,Junyi Zhu,Jing Wang,Xianhui Chen,Yuanbo Zhang +12 more
TL;DR: In this paper, it was shown that the itinerant ferromagnetic order persists in Fe3GeTe2 down to the monolayer with an out-of-plane magnetocrystalline anisotropy.
Journal Article
Electrical switching of an antiferromagnet
TL;DR: Electrical writing is combined in solid-state memory with electrical readout and the stored magnetic state is insensitive to and produces no external magnetic field perturbations, which illustrates the unique merits of antiferromagnets for spintronics.

Room-temperature ferromagnetism in graphite driven by two-dimensional networks of point defects
TL;DR: In this article, a systematic magnetic force microscope study indicates that ferromagnetism in graphite is the result of localized spins that arise at grain boundaries, which usually only occurs in materials containing elements that form covalent 3d and 4f bonds.

Pressure-controlled interlayer magnetism in atomically thin CrI3.
Tingxin Li,Shengwei Jiang,Nikhil Sivadas,Zefang Wang,Yang Xu,Daniel Weber,Joshua E. Goldberger,Kenji Watanabe,Takashi Taniguchi,Craig J. Fennie,Kin Fai Mak,Jie Shan +11 more
TL;DR: In this paper, pressure-induced changes in the magnetic order of atomically thin van der Waals crystals are revealed and attributed to changes in stacking arrangement, and the interlayer ferromagnetic ground state is established in bulk CrI3 but not observed in native exfoliated thin films.
Journal Article
Atomic-scale control of graphene magnetism by using hydrogen atoms
TL;DR: Hollen and Gupta as mentioned in this paper showed that the adsorption of a single hydrogen atom on graphene induces a magnetic moment characterized by a ~20 millielectron volt spin-split state at the Fermi energy.

Enhanced magnetoresistance in layered magnetic structures with antiferromagnetic interlayer exchange
TL;DR: The electrical resistivity of Fe-Cr-Fe layers with antiferromagnetic interlayer exchange increases when the magnetizations of the Fe layers are aligned antiparallel, much stronger than the usual anisotropic magnetoresistance.
