Abstract

Recently the electronic and magnetic structure of the MoS2-graphene heterostructure epitaxially grown on ferromagnetic Co(0001) was investigated using different experiemental methods accompanied by density functional theory (DFT) calculations [Voroshnin et al., ACS Nano 2022, 16, 7448]. Despite the large distance between the S-terminated Co(0001) surface and Mo atoms of ≈8.3 Å, a sizeable magnetically induced spin-splitting of ≈20 meV for the MoS2-derived valence band states at the Γ point was found and supported by the DFT calculations. Our present realistic large-scale DFT calculations performed for different MoS2-graphene-Co interfaces (with and without inclusion of interface S atoms) rule out the possibility to induce any sizeable magnetic moment in MoS2 layers and the respective spin-splitting of the MoS2-derived bands. It is explained by the large distances between Mo and Co atoms in all cases and that magnetic interaction between them is screened by S and C layers in the considered systems.
