L10-ordered FePd alloy is a ferromagnetic metal with high magnetic anisotropy and low magnetic damping constant, attracting attention as a material for spintronics applications. In this study, we predict the detailed atomic-scale structure and composition of FePd and 2D material interfaces using first-principles electronic state calculations. At the FePd/graphene interface, Fe atomic layers appear on the surface, showing different behavior from the Pd surface in a vacuum. Furthermore, this presentation will discuss the interface with transition metal dichalcogenide (TMDC) based 2D materials.
