Two-dimensional (2D) magnets have gained significant interest following the discovery of prominent materials such as CrI3, Cr2Ge2Te6, and Fe3GeTe2, which hold promise for state-of-the-art applications in spintronics and nanoelectronics. In particular, 2D magnetic heterostructures enable precise control over magnetic properties and electronic behavior by manipulating the interfaces between the stacked layers. Such magnetic heterostructures, characterized by their high sensitivity and performance, play a pivotal role in providing the foundation for devices like magnetic tunnel junctions (MTJs) and spin valves, which enable critical applications such as magnetic random-access memory (MRAM) and hard disc drives (HDDs). The interlayer distance within heterostructures dictates magnetic coupling strength and electronic properties. Modulating this distance enables control over magnetic properties and facilitates the emergence of chiral magnetic structures. Due to the broken inversion symmetry together with a strong spin-orbit coupling, the significant Dzyaloshinskii-Moriya interaction (DMI) is induced at the interface of the heterostructures, which may stabilize the chiral magnetic textures. DMI driven topological chiral magnetic structures, especially skyrmions, provide high density and low energy consumption in race-track memory devices and have attracted much attention in recent years with the potential to replace conventional magnetic domain walls.
