Stern–Gerlach experiment - Wikipedia.

We proposed valley-coupled spintronic devices based on monolayer WSe2 that utilize Valley-Spin Hall (VSH) effect to switch nano-magnets. The unique features of the proposed device are (a) the ability to switch magnets with perpendicular magnetic anisotropy (PMA) and (b) an integrated gate that can modulate the charge/spin current flow. A leading contender for next-generation memories is a spintronic device that stores data in a small magnet controlled with an electric current or field via the spin Hall effect (SHE). SHE is a mechanism by which materials convert an input electric current into an output spin current.

Spin Hall effect - Wikipedia.

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. Recently, a spin Hall device has been reported that utilizes electrical injection from a ferromagnet/semiconductor tunnel contact and demonstrates electrical spin detection by iSHE and by the.

[1506.05606] Spin Hall Effect measurement techniques.

The spin Hall effect is an electronic transport phenomenon giving rise to the accumulation of spin-polarized electrons on the surfaces of a sample carrying electric current. Such a charge-to-spin conversion process originates in materials with a large spin-orbit interaction, which is an interaction of an electron's spin with its motion. The spin Hall effect is of current interest from a fundamental and a device application point of view. Most importantly, the spin Hall effect allows to transfer an electrical charge current into a pure spin current, i.e. a current carrying only (spin) angular momentum without an accompanying charge current.

Cryogenic Memory Architecture Integrating Spin Hall Effect based.

The theoretical prediction of the intrinsic spin Hall effect in metals and insulators (1–3) has generated great interest in the field of spintronics, because this effect allows direct electric manipulation of the spin degrees of freedom without a magnetic field, and the resulting spin current can flow without dissipation. These properties. 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 phenomenon, and the role that several of the spin Hall devices have had in the demonstration of spintronic functionalities and physical phenomena. Spin Hall Effect is relativistic quantum mechanical effect which enables non-magnetic materials show magnetic phenomena without the application of a magnetic field. With spin Hall Effect, one can realize spintronics devices operating purely on electrical and optical means and eliminate the use of ferromagnets which have associated fringe fields. In this review article, we present the.

Spin Hall Effect Device for Magnetic Sensor Application | IEEE.

The spin Hall effect represents an exotic state of matter in which a 2D material conducts electricity along its edge in a way that drastically reduces dissipation. To show this, the researchers used first-principle calculations and found that the materials also feature a large band gap, which reduces undesirable conduction through the bulk. Spin–orbit coupling lies at the core of condensed matter. It is central to magnetism and spintronics, where it drives magnetic anisotropy [1], spin relaxation [2], magnetic damping [3], anisotropic magnetoresistance [4], and anomalous Hall effect [5]. Quite surprisingly, in spite of its already long history, this fundamental interaction has.
