We perform a comparative study of the spin relaxation by spin-orbit coupling induced from adatoms (hydrogen and fluorine) in graphene. Two methods are applied, giving consistent results: a full quantum transport simulation of a graphene nanoribbon, and a T-matrix calculation using Green's functions for a single adatom in graphene. For hydrogenated graphene the dominant spin-orbit term for spin relaxation is PIA, the hitherto neglected interaction due to pseudospin inversion asymmetry. In…

Ab initio modelling of spin relaxation lengths in disordered graphene nanoribbons.
TLDR
This study is conducted at singular ribbon lengths entirely from fully ab initio methods, providing indirectly evidence that the Dyakonov-Perel spin relaxation mechanism might be the dominant at low concentrations as well as the observation of oscillations in the spin-polarization.
Spin relaxation in disordered graphene: Interplay between puddles and defect-induced magnetism
Abstract We study the spin relaxation in graphene due to magnetic moments induced by defects. We propose and employ in our studies a microscopic model that describes magnetic impurity scattering
Spin relaxation in fluorinated single and bilayer graphene
We present a joint experiment-theory study on the role of fluorine adatoms in spin and momentum scattering of charge carriers in dilute fluorinated graphene and bilayer graphene. The experimental
Tuning the spintronic properties of graphene with atomically precise Au clusters
Spin relaxation is investigated in lateral nonlocal graphene spin valves with increasing densities of soft-landed Au3 and Au6 clusters. It is found that both gold clusters scatter spins via the
Absence of a giant spin Hall effect in plasma-hydrogenated graphene
The weak spin-orbit interaction in graphene was predicted to be increased, e.g., by hydrogenation. This should result in a sizable spin Hall effect (SHE). We employ two different methods to examine
Determination of the spin-lifetime anisotropy in graphene using oblique spin precession
TLDR
The spin-lifetime anisotropy of graphene on silicon oxide is independent of carrier density and temperature down to 150 K, and much weaker than previously reported, which indicates that the spin relaxation is driven by magnetic impurities or random spin-orbit or gauge fields.
Theoretical investigations of orbital and spin-orbital effects in functionalized graphene
Functionalization of graphene with adsorbants offers the possibility to tailor existing properties of graphene and also to introduce new desirable features in the system. The ultimate goal is to
Spin Relaxation in s-Wave Superconductors in the Presence of Resonant Spin-Flip Scatterers.
TLDR
This work investigates the relaxation of quasiparticle spins in graphene proximitized by an s-wave superconductor in the presence of resonant magnetic and spin-orbit active impurities and results are opposite to the Hebel-Slichter expectation: the spin relaxation decreases with decreasing temperature.
Spin relaxation, Josephson effect and Yu-Shiba-Rusinov states in superconducting bilayer graphene
Bilayer graphene has two non-equivalent sublattices and, therefore, the same adatom impurity can manifest in spectrally distinct ways—sharp versus broad resonances near the charge neutrality—
Interplay of resonant states and Landau levels in functionalized graphene
Adsorbates can drastically alter physical properties of graphene. Particularly important are adatoms and admolecules that induce resonances at the Dirac point. Such resonances limit electron
