In this article, the changes in the electronic structure induced by lattice defects in graphene planes were studied and it was shown that lattice distortions give rise to localized states at the Fermi level.
Abstract
We study the changes in the electronic structure induced by lattice defects in graphene planes. In many cases, lattice distortions give rise to localized states at the Fermi level. Electron-electron interactions lead to the existence of local moments. The RKKY interaction between these moments is always ferromagnetic, due to the semimetallic properties of graphene.

Spin relaxation times in disordered graphene

TL;DR: In this article, the authors considered two mechanisms of spin relaxation in disordered graphene, i) spin relaxation due to curvature spin orbit coupling caused by ripples, and ii) spin relaxations due to the interaction of the electronic spin with localized magnetic moments at the edges.

Electric Field Effect in Atomically Thin Carbon Films

TL;DR: Monocrystalline graphitic films are found to be a two-dimensional semimetal with a tiny overlap between valence and conductance bands and they exhibit a strong ambipolar electric field effect.

Band Structure of Graphite

TL;DR: In this paper, a perturbation calculation which starts with wave functions of the two-dimensional lattice and is applied to the three-dimensional graphite lattice is described and general features of the structure of the $\ensuremath{\pi}$ bands in the neighborhood of the zone edge are obtained and are expressed in terms of appropriate parameters.

Magnetic nanographite

TL;DR: In this paper, it was shown that hydrogenation of nanographite is able to induce finite magnetization and demonstrated the spontaneous magnetism of a graphene ribbon in which each carbon is bonded to two hydrogen atoms at one edge and to a single hydrogen atom at another edge.
