Atomic-scale control of graphene magnetism by using hydrogen atoms
Atomic-scale control of graphene magnetism by using hydrogen atoms
Isolated hydrogen atoms absorbed on graphene are predicted to induce magnetic moments. Here we demonstrate that the adsorption of a single hydrogen atom on graphene induces a magnetic moment characterized by a ~20 meV spin-split state at the Fermi energy. Our scanning tunneling microscopy (STM) experiments, complemented by first-principles calculations, …
