研究了石墨烯平面中晶格缺陷引起的电子结构的变化。在许多情况下，晶格扭曲导致费米能级上的局域态。电子-电子相互作用导致局部力矩的存在。由于石墨烯的半金属性质，这些力矩之间的RKKY相互作用总是铁磁性的。
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.
