Tight-binding study of nonmagnetic-defect-induced magnetism in graphene
This review describes a study of nonmagnetic-defect-induced magnetism of graphene on the basis of a tight-binding model. A vacancy induces a quasilocalized impurity state at the chemical potential around itself, and it leads to formation of local magnetic moments. Connection between a quasilocaliz...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | This review describes a study of nonmagnetic-defect-induced magnetism of graphene on the basis of a
tight-binding model. A vacancy induces a quasilocalized impurity state at the chemical potential around itself,
and it leads to formation of local magnetic moments. Connection between a quasilocalized state around
a vacancy and the edge localized states near a zigzag edge is studied in detail. Magnetism associated with
many vacancies and edge structures is also reviewed. Some new results of magnetism associated with many
vacancies are presented. |
