Spin Hall Effect

, 2017
This chapter discusses the spin Hall effect that occurs during spin injection from a ferromagnet to a nonmagnetic conductor in nanostructured devices. This provides a new opportunity for investigating AHE in nonmagnetic conductors. In ferromagnetic materials, the electrical current is carried by up-spin and downspin electrons, with the flow of up-spin ...

Spin Hall effect devices

Nature Materials, 2012
The spin Hall effect is a relativistic spin-orbit coupling phenomenon that can be used to electrically generate or detect spin currents in non-magnetic systems. Here we review the experimental results that, since the first experimental observation of the spin Hall effect less than 10 years ago, have established the basic physical understanding of the ...

Spin Hall effects

Reviews of Modern Physics, 2015
In solid-state materials with strong relativistic spin-orbit coupling, charge currents generate transverse spin currents. 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.

The intrinsic spin Hall effect

2005 International Conference on MEMS,NANO and Smart Systems, 2005
Summary form only given, as follows: a recent theory predicts that dissipationless spin currents can be induced purely by an electric field in conventional semiconductors. The dissipationless spin current is derived from a novel topological structure in momentum space, is independent of the sample disorder and leads to the intrinsic spin Hall effect ...

Spin Hall Effect in the Presence of Spin Diffusion

Physical Review Letters, 2000
Hirsch [Phys. Rev. Lett. 83, 1834 (1999)] recently proposed a spin Hall effect based on the anomalous scattering mechanism in the absence of spin-flip scattering. Since the anomalous scattering causes both anomalous currents and a finite spin-diffusion length, we derive the spin Hall effect in the presence of spin diffusion from a semiclassical ...

Spin-Orbit Optical Hall Effect

Physical Review Letters, 2019
The optical Hall effect manifests itself as angular momentum separation induced by the photonic spin-orbit interaction. Such a celebrated Hall effect, at the mercy of the angular momentum conservation law, has attracted tremendous interest owing to its science and potential applications in precision measurements, material characterizations, and ...

Photonic Spin Hall Effect at Metasurfaces

Science, 2013
Photonic Spin Hall Effect When charged carriers move in a magnetic field, they are deflected—an effect known as the Hall effect. Electrons possess charge and spin, a property related to magnetism. The symmetry of electromagnetism then allows for a spin Hall effect whereby the spin is deflected by an electric field.

Observation of the Spin Hall Effect in Semiconductors

Science, 2004
Electrically induced electron-spin polarization near the edges of a semiconductor channel was detected and imaged with the use of Kerr rotation microscopy. The polarization is out-of-plane and has opposite sign for the two edges, consistent with the predictions of the spin Hall effect.

NONCOMMUTATIVE DESCRIPTION OF SPIN HALL EFFECT

International Journal of Geometric Methods in Modern Physics, 2009
We propose an approach based on a generalized quantum mechanics to deal with the basic features of the intrinsic spin Hall effect. This can be done by considering two decoupled harmonic oscillators on the noncommutative plane and evaluating the spin Hall conductivity. Focusing on the high frequency regime, we obtain a diagonalized Hamiltonian.

Spin current and spin Hall effects

OSA Workshop on Entanglement and Quantum Decoherence, 2008
In terms of SU(2) Yang-Mills field formulism, we give a nature definition of spin current for the systems with Rashba or Dresselhaus spin-orbit couplings etc., and we obtain a covariant form of continuity equations for the corresponding spin current [1].
