Anisotropic spin relaxation in graphene.
Spin relaxation in graphene is investigated in electrical graphene spin valve devices in the nonlocal geometry. Ferromagnetic electrodes with in-plane magnetizations inject spins parallel to the graphene layer. They are subject to Hanle spin precession under a magnetic field B applied perpendicular to the graphene layer. Fields above 1.5 T force the magnetization direction of the ferromagnetic ...
متن کاملPseudospin-driven spin relaxation mechanism in graphene
The prospect of transporting spin information over long distances in graphene, possible because of its small intrinsic spin– orbit coupling (SOC) and vanishing hyperfine interaction, has stimulated intense research exploring spintronics applications. However, measured spin relaxation times are orders of magnitude smaller than initially predicted, while the main physical process for spin dephasi...
متن کاملTheory of spin-orbit induced spin relaxation in functionalized graphene
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 spinorbit term for spin r...
متن کاملSpin-orbit-mediated spin relaxation in ballistic graphene materials
Most of the work on understanding spin relaxation in graphene for spintronic applications relies on the assumption that spin polarization is lost due to scattering and dephasing processes. Here, we present results of a recent theoretical study of spin dynamics of supported graphene in the ballistic regime [1]. This can be relevant in high-quality devices where electron scattering no longer domi...
متن کاملCurrent relaxation due to hot carrier scattering in graphene
In this paper, we present direct time-domain investigations of the relaxation of electric currents in graphene due to hot carrier scattering. We use coherent control with ultrashort optical pulses to photoinject a current and detect the terahertz (THz) radiation emitted by the resulting current surge. We pre-inject a background of hot carriers using a separate pump pulse, with a variable delay ...
