Perpendicular magnetic anisotropy in a single Dy adatom ferrimagnet

Original language description

Rare-earth atom adsorption on suitable surfaces is a viable pathway for creating atomic scale magnetic information storage in the most fundamental unit of matter. Dysprosium (Dy) exibits a large magnetic anisotropy and can be protected against quantum tunneling in a uniaxial crystal field. Among possible substrates graphene (Gr)/Ni(111) has been set forward as the optimal scaffold where to deposit adatoms.We address the electronic and magnetic structure, and the magnetic anisotropy of Dy@Gr/Ni(111) making use of the DFT+U(HIA) methodology, and 3x3x1 supercell model with 36 Ni-atoms, and the layer of graphene with 18 C atoms on the top of Ni surface
