Symmetry-protected difference between spin Hall and anomalous Hall effects of a periodically driven multiorbital metal

open access: yesCommunications Physics, 2023
Nonequilibrium quantum states can be controlled via the driving field in periodically driven systems. Such control, which is called Floquet engineering, has opened various phenomena, such as the light-induced anomalous Hall effect.

Voltage-driven gigahertz frequency tuning of spin Hall nano-oscillators

open access: yesNature Communications, 2022
Spin-hall nano-oscillators are a variation on spin-torque nano-oscillators, where the spin-Hall effect is used to drive oscillations, however past examples have had limited frequency tunability.

Giant orbital Hall effect and orbital-to-spin conversion in 3d, 5d, and 4f metallic heterostructures

open access: yesPhysical Review Research, 2022
The orbital Hall effect provides an alternative means to the spin Hall effect to convert a charge current into a flow of angular momentum. Recently, compelling signatures of orbital Hall effects have been identified in 3d transition metals.

Negative spin Hall magnetoresistance of normal metal/ferromagnet bilayers

open access: yesNature Communications, 2020
In normal metal/ferromagnet bilayers, the spin Hall magnetoresistance originating from the spin Hall effect of normal metal possesses positive sign regardless of the sign of spin Hall conductivity of normal metal.

Enhanced Spin Hall Shift by Multipoles of Different Orders in Spherical Particles

open access: yesPhotonics, 2023
The spin–orbit interaction of light is universal in the process of light scattering, and an important aspect is the spin Hall effect. The spin Hall effect of light also exists in a three-dimensional (3D) system.

Controlling spin current polarization through non-collinear antiferromagnetism

open access: yesNature Communications, 2020
In the typical spin-hall effect, spin-current, charge current, and spin polarisation are all mutually perpendicular, a feature enforced by symmetry. Here, using an anti-ferromagnet with a triangular spin structure, the authors demonstrate a spin-hall ...

Geometric phase for multidimensional manipulation of photonics spin Hall effect and helicity-dependent imaging

open access: yesNanophotonics, 2020
The spin Hall effect of light, associated with spin-orbit interactions, describes a transport phenomenon with optical spin-dependent splitting, leading to a plethora of applications such as sensing, imaging, and spin-controlled nanophotonics.

W thickness dependence of spin Hall effect for (W/Hf)-multilayer electrode/CoFeB/MgO systems with flat and highly (100) oriented MgO layer

open access: yesAIP Advances, 2021
We investigated spin-Hall effect (SHE) and degree of MgO (100) orientation in artificially synthesized (W/Hf)-multilayer/CoFeB/MgO systems with various W thicknesses. We found that the artificially synthesized multilayer systems can enhance the spin-Hall

Ferromagnetic-electrodes-induced Hall effect in topological Dirac semimetals

open access: yesPhysical Review Research, 2021
We propose an unconventional type of Hall effect in a topological Dirac semimetal with ferromagnetic electrodes. The topological Dirac semimetal itself has time-reversal symmetry, whereas attached ferromagnetic electrodes break it, causing the large Hall
