Theory of Scanning Tunneling Spectroscopy of Magnetic Adatoms in Graphene
Bruno Uchoa, Ling Yang, S. -W. Tsai +2
We examine theoretically the signatures of magnetic adatoms in graphene probed by scanning tunneling spectroscopy (STS). When the adatom hybridizes equally with the two graphene su…
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…
Magnetic structure and critical behavior of GdRhIn: resonant x-ray diffraction and renormalization group analysis
E. Granado, B. Uchoa, A. Malachias +3
The magnetic structure and fluctuations of tetragonal GdRhIn5 were studied by resonant x-ray diffraction at the Gd LII and LIII edges, followed by a renormalization group analysis…
Commensurability Transition and Stripe Phases in the Ginzburg-Landau Theory
B. Uchoa, G. G. Cabrera
We phenomenologically describe the thermodynamics of charge and spin density waves in doped high- oxides. We have explicitly calculated stable non-homogeneous solutions in t…
