Discovery of atomically-thin layered two dimensional (2D) van der Waals materials have attracted considerable attention due to their emerging properties from electronic and optical viewpoints, while 2D ferromagnetism, which plays an important role on 2D spintronics, has been unexplored until recent studies on semiconducting Cr₂Te₂Te₆, CrI₃, and metallic Fe₃GeTe₂. Combining ferromagnetic properties with electronic and optical properties could open huge application opportunities in magnetoelectric and magneto-optics fields. From this point, transitional-metal dichalcogenides (TMDCs) are one of the most promising candidates, which already showed potential in electronic and optoelectronic applications. While currently discovered VSe₂ has only weak ferromagnet with an isotropic feature. Here we will introduce our growth in atomically-thin chromium telluride epitaxial thin films on insulating sapphire substrates, which showed strong ferromagnetic behavior with robust out-of-plane anisotropy.
