Localized Magnetic States in Graphene
Bruno Uchoa, Valeri N. Kotov, N. M. R. Peres +1
We examine the conditions necessary for the presence of localized magnetic moments on adatoms with inner shell electrons in graphene. We show that the low density of states at the…

Weak ferromagnetism and spiral spin structures in honeycomb Hubbard planes
M A N Araujo, N M R Peres
Within the Hartree Fock- RPA analysis, we derive the spin wave spectrum for the weak ferromagnetic phase of the Hubbard model on the honeycomb lattice. Assuming a uniform magnetiza…
