Theoretical studies of 2D-materials adsorbed onto magnetic surfaces — •Nicolae Atodiresei, Vasile Caciuc, and Stefan Blügel — Peter Grünberg Institut (PGI-1) and Institute for Advanced Simulation (IAS-1), Forschungszentrum Jülich, Germany

Using density functional theory calculations we explored how the interaction between magnetic surfaces with 2D materials as graphene (Gr) and transition metal dichalcogenites (TMDs) monolayers reciprocally modifies their electronic and magnetic properties. On one hand, the 2D material–substrate chemisorption induces a spin–unbalanced electronic structure of the 2D material with specific system dependent features. On the other hand, the strong hybridization at the hybrid interface leads to an increase of the magnetic exchange interactions between the surface magnetic atoms as compared to those of the clean substrate. Similarly to the case of organic molecules adsorbed on magnetic surfaces, the presence of the magnetic hardening effect at the 2D material–substrate interface emphases the generality of this adsorbate induced–effect on magnetic surfaces.
