Vacancy-induced magnetism in graphene and graphene ribbons
Vacancy-induced magnetism in graphene and graphene ribbons
We address the electronic structure and magnetic properties of vacancies and voids both in graphene and graphene ribbons. By using a mean-field Hubbard model, we study the appearance of magnetic textures associated with removing a single atom (vacancy) and multiple adjacent atoms (voids) as well as the magnetic interactions between …
