In recent years, two-dimensional materials have attracted attention as tunnel barrier materials in magnetic tunnel junctions. This study performed first-principles calculations to predict the atomic structure at the interface between two-dimensional materials(graphene and h-BN) and ferromagnetic material(FeNi). Calculations varying the composition of FeNi surfaces and the adsorption sites of the two-dimensional materials revealed stable structures. Furthermore, analysis of the electronic density of states showed electron transfer from the metal substrate to graphene and observed orbital hybridization between Fe and C atoms.
