Abstract

Fe₃GaTe₂ (FGaT), a two-dimensional layered ferromagnetic metal, exhibits a high Curie temperature (~360 K) along with strong perpendicular magnetic anisotropy. This work demonstrates large-scale growth of epitaxial FGaT thin films on single-crystalline graphene/SiC templates using molecular beam epitaxy, yielding continuous FGaT/graphene van der Waals heterostructures. Structural characterization confirms high crystalline quality, while temperature-dependent magnetization and anomalous Hall measurements reveal robust perpendicular magnetic anisotropy and Curie temperatures well above room temperature, reaching up to 400 K. X-ray absorption and XMCD further probe the magnetic moment contributions.
