| Résumé: | © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. R. Zbořil and co-workers show that doping a graphene lattice with sulfur induces magnetic centers which display ferromagnetic order below ≈62 K. As described on page 5045, sulfur doping promotes magnetically active configurations resembling the gamma-thiothiapyrone motif. Enhanced magnetic properties of sulfur-doped graphene are attributed to two unpaired electrons from each sulfur atom injected into the graphene conducting band where they are delocalized between the S and C atoms |
