Above-Room-Temperature Ferromagnetism in Large-Scale Epitaxial Fe<sub>3</sub>GaTe<sub>2</sub>/Graphene van der Waals Heterostructures.

Furthermore, X-ray absorption and X-ray magnetic circular dichroism spectra provide insight into the spin and orbital magnetic moment contributions, further validating the high T C and robust PMA. These findings are highly significant for the future development of high-performance spintronic devices based on 2D heterostructures, with potential applications in next-generation data storage, logic processing, and quantum technologies.
