▎ 摘  要

Changes in the magnetic property of the Mn transition metal on graphene were observed using density functional calculations (DFT) where the Mn/graphene system was enforced by an external electric field. The magnetic moment of the Mn adatom on graphene showed continuous changes as a result of the external field. Analysis of the charge redistribution of the system revealed that the electrons are partially transferred between graphene and the Mn adatom from the effect of the external electric field. According to the density of states (DOS) data, the transferred charge originates from the electrons in 3d spin down states. In this study, it was found that the external electric field affected the changes in the electronic structure of the outermost shell of the Mn adatom, and this change resulted in change in the magnetic moment.
