Giant Spin-Hall Effect Induced by the Zeeman Interaction in Graphene
TLDR
A new approach to generate and detect spin currents in graphene is proposed, based on a large spin-Hall response arising near the neutrality point in the presence of an external magnetic field, which is viable for spintronics applications.Abstract:
We propose a new approach to generate and detect spin currents in graphene, based on a large spin-Hall response arising near the neutrality point in the presence of an external magnetic field. Spin currents result from the imbalance of the Hall resistivity for the spin-up and spin-down carriers induced by the Zeeman interaction, and do not involve a spin-orbit interaction. Large values of the spin-Hall response achievable in moderate magnetic fields produced by on-chip sources, and up to room temperature, make the effect viable for spintronics applications.read more

Spin Hall effects
TL;DR: In solid-state materials with strong relativistic spin-orbit coupling, charge currents generate transverse spin currents as discussed by the authors and the associated spin Hall and inverse spin Hall effects distinguish between charge and spin current where electron charge is a conserved quantity but its spin direction is not.

TL;DR: In this paper, the authors reported a strong Anderson localization and the corresponding metal-insulator transition in ultra-high-quality graphene, where the transition is controlled externally, by changing the carrier density in another graphene layer placed at a distance of several nm and decoupled electrically.

TL;DR: In this paper, it was shown that applying a local magnetic field parallel to an injected current induces a valley imbalance that diffuses over long distances, and a probe magnetic field can then convert this imbalance into a measurable voltage drop far from source and drain.

TL;DR: In this article, vorticity is reported as a signature feature of electron viscosity in graphene, which leads to negative nonlocal resistance, which can be observed experimentally.
