A Computational Study of Spin Hall Effect Device Based on 2D Materials.

This paper proposes a scalable SNG based on the spin-Hall-effect (SHE), which is capable of generating multiple independent stochastic streams simultaneously. The design takes advantages of the efficient charge-to-spin conversion from the Spin-Hall material and the intrinsic stochasticity of nanomagnets.

A potential difference, known as the Hall voltage will be generated between both sides of the plate which can be measured using a meter. The Hall voltage represented as V H is given by the formula: V H = I B q n d. Here, I is the current flowing through the sensor. B is the magnetic Field Strength. q is the charge.

Here, we show that a single spin-orbit torque device composed of a Ta/CoFeB/MgO heterostructure can detect a vector magnetic field. In-plane and out-of-plane field components lead to the displacement of domain walls in the CoFeB layer, modulating the associated anomalous Hall effect resistance. Abstract. g eff ↑ ↓ of the CoFeB/Ir interface is 30 nm − 2, and the spin Hall angle of iridium has the same sign as the one of platinum and is evaluated at 26% of the one of platinum. The value of the spin Hall angle found is 7.7% for Pt and 2% for Ir. These relevant parameters shall be useful to consider Ir in new concepts and devices.

One of its main applications is the electrical detection of spin currents, and for this, the inverse spin Hall effect (ISHE) has become one of the preferred methods. We studied the thickness dependence of the ISHE in iridium oxide (IrO2) thin films, producing spin currents by means of the spin Seebeck effect in γ−Fe2O3/IrO2 bilayers prepared. 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 phenomenon, and the. 3-terminal magnetic circuits and devices based on the spin-transfer torque (STT) effect via a combination of injection of spin-polarized electrons or charged particles by using a charge current in a spin Hall effect metal layer coupled to a free magnetic layer and application of a gate voltage to the free magnetic layer to manipulate the magnetization of the free magnetic layer for various.

In this paper, we investigate four CuAu-I-type metallic antiferromagnets for their potential as spin current detectors using spin pumping and inverse spin Hall effect. Nontrivial spin Hall effects were observed for FeMn, PdMn, and IrMn while a much higher effect was obtained for PtMn. Using thickness-dependent measurements, we determined the.

Valley-related multiple Hall effect in two-dimensional (2D) lattice is a fundamental transport phenomenon in the fields of condensed matter physics and materials science. Most proposals for its realization are limited to toy models or extrinsic effects. Here, based on a tight-binding model and first-principles calculations, we report the discovery of intrinsic valley-related multiple Hall.

Spin-Hall Effect: From the Ballistic to the Diffusive Regime.

We are currently working on spin Hall effect in graphene devices. We have pioneered novel detection techniques [Nature 442, 176 (2006)] that led to the first demonstration of direct detection of spin currents, and the first electrical measurements of the (reciprocal) spin Hall effect (SHE). The SHE is the generation in a non-magnetic sample of. A strong photonic SHE resulting in a measured large splitting of polarized light at metasurfaces is reported, which may provide a route for exploiting the spin and orbit angular momentum of light for information processing and communication. Photonic Spin Hall Effect When charged carriers move in a magnetic field, they are deflected—an effect known as the Hall effect. Electrons possess. The spin-Hall effect has recently attracted a lot of attention and a central question is whether the effect is due to the intrinsic spin-orbit interaction or due to spin-asymmetric scattering by extrinsic impurities.... average over the energy range This work was supported by the MARCO focus center on Materials, Structures and Devices and the.

Protecting intellectual property (IP) in electronic circuits has become a serious challenge in recent years. Logic locking/encryption and layout camouflaging are two prominent techniques for IP protection. Most existing approaches, however, particularly those focused on CMOS integration, incur excessive design overheads resulting from their need for additional circuit structures or device.
