Nonmagnetic-Defect-Induced Magnetism in Graphene
arXiv:cond-mat/0703570 · doi:10.1143/JPSJ.76.064713
Abstract
It is shown that a strong impurity potential induces short-range antiferromagnetic (ferrimagnetic) order around itself in a Hubbard model on a half-filled honeycomb lattice. This implies that short-range magnetic order is induced in monolayer graphene by a nonmagnetic defect such as a vacancy with full hydrogen termination or a chemisorption defect.
