“…The easy out‐of‐plane magnetization axis in single‐layer Fe 3 GeTe 2 means that this material belongs to the family of 2D Ising magnets. Similar to many other materials, the MAE can be tuned by applying strain . The MAE increases with increasing tensile strain, and the total magnetic moment follows the same trend as the strain (Figure c,d), indicating strong magnetostriction in single‐layer Fe 3 GeTe 2 20d.…”

2D van der Waals (vdW) magnets, which present intrinsic ferromagnetic/antiferromagnetic ground states at finite temperatures down to atomic‐layer thicknesses, open a new horizon in materials science and enable the potential development of new spin‐related applications. The layered structure of vdW magnets facilitates their atomic‐layer cleavability and magnetic anisotropy, which counteracts spin fluctuations, thereby providing an ideal platform for theoretically and experimentally exploring magnetic phase transitions in the 2D limit. With reduced dimensions, the susceptibility of 2D magnets to a large variety of external stimuli also makes them more promising than their bulk counterpart in various device applications. Here, the current status of characterization and tuning of the magnetic properties of 2D vdW magnets, particularly the atomic‐layer thickness, is presented. Various state‐of‐the‐art optical and electrical techniques have been applied to reveal the magnetic states of 2D vdW magnets. Other emerging 2D vdW magnets and future perspectives on the stacking strategy are also given; it is believed that they will excite more intensive research and provide unprecedented opportunities in the field of spintronics.

Computationally characterizing magnetic properies of novel two-dimensional (2D) materials serves as an important first step of exploring possible applications. Using density-functional theory, we show that single-layer Fe3GeTe2 is a potential 2D material with sufficiently low formation energy to be synthesized by mechanical exfoliation from the bulk phase with a van der Waals layered structure. In addition, we calculated the phonon dispersion demonstrating that single-layer Fe3GeTe2 is dynamically stable. Furthermore, we find that similar to the bulk phase, 2D Fe3GeTe2 exhibits a magnetic moment that originates from a Stoner instability. In contrast to other 2D materials, we find that single-layer Fe3GeTe2 exhibits a significant uniaxial magnetocrystalline anisotropy energy of 920 µeV per Fe atom originating from spin-orbit coupling. Finally, we show that applying biaxial tensile strains enhance the anisotropy energy, which reveals strong magnetostriction in single-layer Fe3GeTe2 with a sizable magneostrictive coefficient. Our results indicate that single-layer Fe3GeTe2 is potentially useful for magnetic storage applications.

“…This is because it is well known that the 3d xy , 3d zx , and 3d yz orbitals affect the SOC, which contributes to MA. In previous research [43], the PMA increase by the minority spin of the 3d x 2 − y 2 and 3d xy orbitals. In the explanation above, the DOS of Pd-rich A and Co-rich B showed difference states in 3d xy , but these structures did not show a difference in the 3d x 2 − y 2 orbital.…”
