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

AIP 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

Effects of spin symmetry breaking in topological insulators [PDF]

, 2015
Topological insulators are one of the most thoroughly investigated systems in condensed matter physics over the last years. In these systems, a prominent role is inevitably taken by time-reversal symmetry, which leads to Kramers theorem and symmetry ...

Ferromagnetic-electrodes-induced Hall effect in topological Dirac semimetals

Physical 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

Spin pumping in ferromagnet-topological insulator-ferromagnetheterostructures [PDF]

, 2015
Topological insulators (TIs) are enticing prospects for the future of spintronics due to their large spin-orbit coupling and dissipationless, counter-propagating conduction channels in the surface state.

Observation of the antiferromagnetic spin Hall effect

, 2021
The discovery of the spin Hall effect1 enabled the efficient generation and manipulation of the spin current. More recently, the magnetic spin Hall effect2,3 was observed in non-collinear antiferromagnets, where the spin conservation is broken due to the

Spin transport of excitons [PDF]

, 2009
We report on observation of the spin transport of spatially indirect excitons in GaAs/AlGaAs coupled quantum wells (CQW). Exciton spin transport over substantial distances, up to several micrometers in the present work, is achieved due to orders of ...

Spin-Hall conductivity and Hall angle in a two-dimensional system with impurities in the presence of spin–orbit interactions

Scientific Reports, 2022
We investigate the spin-torque-dependent Spin Hall phenomenon in a two-dimensional tight-binding system in the presence of Rashba and Dresselhaus spin–orbit interactions and random static impurities.

Spin Hall effect on the kagome lattice with Rashba spin-orbit interaction

, 2009
We study the spin Hall effect in the kagome lattice with Rashba spin-orbit coupling. The conserved spin Hall conductance sigma(s)(xy) (see text) and its two components, i.e., the conventional term sigma(s0)(xy) and the spin-torque-dipole term sigma(s tau)

Controllable spin current in van der Waals ferromagnet Fe_{3}GeTe_{2}

Physical Review Research, 2021
The control of spin current is pivotal for spintronic applications, especially for spin-orbit torque devices. The spin Hall effect is a prevalent method to generate spin current. However, it is difficult to manipulate its spin polarization in a nonmagnet.
