WebMar 22, 2013 · The spin Hall effect (SHE) of light is very weak because of the extremely small photon momentum and spin-orbit interaction. Here, we report a strong photonic SHE resulting in a measured large splitting of polarized light at metasurfaces. Webreport a giant spin Hall effect (SHE) in b-tantalum that generates spin currents intense enough to induce efficient spin-torque switching of ferromagnets at room temperature. …
Collinear Rashba-Edelstein effect in non-magnetic chiral materials
WebApr 24, 2024 · However, the microscopic origin of the SOT is being debated, with the spin Hall effect (SHE) due to nonlocal spin currents and the spin Rashba-Edelstein effect (SREE) due to local spin... The spin Hall effect (SHE) is a transport phenomenon predicted by Russian physicists Mikhail I. Dyakonov and Vladimir I. Perel in 1971. It consists of the appearance of spin accumulation on the lateral surfaces of an electric current-carrying sample, the signs of the spin directions being opposite on the opposing boundaries. … See more The spin Hall effect is a transport phenomenon consisting of the appearance of spin accumulation on the lateral surfaces of a sample carrying electric current. The opposing surface boundaries will have spins of … See more The spin Hall effect (direct and inverse) was predicted by Russian physicists Mikhail I. Dyakonov and Vladimir I. Perel in 1971. They also introduced for the first time the notion of spin current. In 1983 Averkiev and Dyakonov proposed a way to measure … See more The spin current is described by a second-rank tensor qij, where the first index refers to the direction of flow, and the second one to the spin component that is flowing. Thus qxy denotes … See more A transformation of spin currents consisting in interchanging (swapping) of the spin and flow directions (qij → qji) was predicted by Lifshits and Dyakonov. Thus a flow in the x … See more Two possible mechanisms give origin to the spin Hall effect, in which an electric current (composed of moving charges) transforms into a spin current (a current of moving spins without charge flow). The original (extrinsic) mechanism devised by Dyakonov and Perel … See more No magnetic field is needed for spin Hall effect. However, if a strong enough magnetic field is applied in the direction perpendicular to the … See more The direct and inverse spin Hall effect can be monitored by optical means. The spin accumulation induces circular polarization of the emitted light, as well as the Faraday (or Kerr) polarization rotation of the transmitted (or reflected) light.

Webspin-orbit logic [11,12]. The SHE generates a transverse pure spin current when a charge current is applied in a material with strong SOC [1, 2]. Reciprocally, the inverse spin Hall effect (ISHE) is employed as a pure spin current detector because a measurable transverse charge current is created from the pure spin current. WebAug 19, 2015 · The SHE and ISHE enable us to electrically manipulate or detect spin currents. The chapter compares the SHE with other Hall effect. It next replaces the magnetic field with the magnetization. This leads to the anomalous Hall effect (AHE). The mechanisms for the AHE and the SHE are similar. They are classified into extrinsic and … WebAlternative designs for magnetic recording assisted by two spin hall effect (SHE) layers in the write gap Issued July 14, 2024 United States 10,714,136.
