Absence of a giant spin Hall effect in plasma-hydrogenated graphene
Tobias Völkl, Denis Kochan, Thomas Ebnet +8
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 m…
Spin field-effect transistor action via tunable polarization of the spin injection in a Co/MgO/graphene contact
Sebastian Ringer, Matthias Rosenauer, Tobias Völkl +4
We fabricated a non-local spin valve device with Co-MgO injector/detector tunnel contacts on a graphene spin channel. In this device, the spin polarization of the injector contact…
Measuring anisotropic spin relaxation in graphene
Sebastian Ringer, Stefan Hartl, Matthias Rosenauer +5
We compare different methods to measure the anisotropy of the spin-lifetime in graphene. In addition to out-of-plane rotation of the ferromagnetic electrodes and oblique spin prece…
