Stable antiferromagnetic graphone

Density functional modeling of atomic structure and calculation of electronic structure of one-side one-sublattice functionalized graphene (graphone) are performed for hydrogen and fluorine adatoms. Shown that using of fluorine for functionalization not on enhance stability of compound but also provide switch of magnetic ground state from ferro- to antiferromagnetic. Half-metallic ferromagnetic state in fluorine based graphone is also discussed.
