Frustrated magnetic interactions in a cyclacene crystal
R. Ortiz, J. C. Sancho-García, J. Fernández-Rossier
We study the emergence of magnetism and its interplay with structural properties in a two dimensional molecular crystal of cyclacenes, using density functional theory (DFT). Isolat…
Renormalization of spin excitations and Kondo effect in open shell nanographenes
David Jacob, Ricardo Ortiz, Joaquín Fernández-Rossier
We study spin excitations and Kondo effect in open-shell nanographenes, motivated by recent scanning tunneling inelastic spectroscopy experiments. Specifically, we consider three s…
Probing local moments in nanographenes with electron tunneling spectroscopy
Ricardo Ortiz, Joaquín Fernández-Rossier
The emergence of local moments in graphene zigzag edges, grain boundaries, vacancies and sp3 defects has been widely studied theoretically. However, conclusive experimental evidenc…
Excitonic Magneto-Optical Kerr Effect in 2D Transition Metal Dichalcogenides Induced by Spin Proximity
J. C. G. Henriques, G. Catarina, A. T. Costa +2
In this paper we develop the excitonic theory of Kerr rotation angle in a two-dimensional (2D) transition metal dichalcogenide at zero magnetic field. The finite Kerr angle is indu…
Single spin resonance driven by electric modulation of the g factor anisotropy
Alejandro Ferrón, Santiago A. Rodríguez, Sergio S. Gómez +2
We address the problem of electronic and nuclear spin resonance of an individual atom on a surface driven by a scanning tunnelling microscope. Several mechanisms have been proposed…
Enhanced lifetimes of spin chains coupled to chiral edge states
F. Delgado, J. Fernández-Rossier
We consider spin relaxation of finite-size spin chains exchanged coupled with a one dimensional (1D) electron gas at the edge of a Quantum Spin Hall (QSH) insulator. Spin lifetimes…
