In the case of the vertical polarization, the displacement is found to increase with the incident angle and subsequently decrease after ∼ 48 deg, while in the case of the horizontal.

Room-Temperature Spin Hall Effect in Graphene/MoS2 van der.

The interaction between accumulated spins on the surface of a heavy metal (HM) and the magnetization of an adjacent magnetic material leads to various spin phenomena, such as spin-orbit torque, spin pumping, and spin Hall magnetoresistance (SHMR). However, the exploration of device applications based on these spin phenomena is often limited by the low charge-to-spin conversion efficiency of. Oct 17, 2014 · To extract the intrinsic spin Hall angle in Pt by estimating the total spin current injected into NiFe from Pt, the NiFe thickness dependent measurements are performed and the spin diffusion in the NiFe layer is taken into account. The intrinsic spin Hall angle of Pt is determined to be 0.068 at room temperature and is found to be almost. Spin-orbit coupling, the key ingredient of the spin Hall effect, originates from Paul Dirac's famous union of special relativity and quantum mechanics. In 1929, two years after Dirac's theory appeared, Nevill Mott applied it to the problem of scattering spinning electrons off atoms.

Quantum Hall effect can be considered as a two-dimensional TI with one-dimensional edge states. It was later found that the quantum Hall effect originates from the non-trivial topology of the two-dimensional electron wavefunctions under strong magnetic fields.8) This further led to the prediction of a novel quantum Hall effect without Landau levels.

Large spin-to-charge conversion (spin Hall angle) and spin Hall conductivity are prerequisites for development of next generation power efficient spintronic devices. In this context, heavy metals (e.g., Pt, W, etc.), topological insulators, and antiferromagnets are usually considered because they exhibit high spin–orbit coupling (SOC).

Review and Analysis of Measurements of the Spin Hall Effect.

The spin Hall angle, a material parameter that characterizes charge to spin conversion efficiency, scales with the longitudinal resistivity and the spin Hall conductivity. For the intrinsic spin Hall effect, the spin Hall conductivity is determined by the electron band structure ( 4 , 5 ) (i.e., the Berry curvature of the bands near the Fermi. Abstract Spin Hall effects are a collection of relativistic spin-orbit coupling phenomena in which electrical currents can generate transverse spin currents and vice versa. Despite being observed only a decade ago, these effects are already ubiquitous within spintronics, as standard spin-current generators and detectors.
