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 Hall effect of excitons [PDF]
Physical Review B, 2008 Spin Hall effect for excitons in alkali halides and in Cu_2O is investigated theoretically. In both systems, the spin Hall effect results from the Berry curvature in k space, which becomes nonzero due to lifting of degeneracies of the exciton states by exchange coupling.

Inverse spin Hall effect by spin injection [PDF]
Applied Physics Letters, 2007 Motivated by a recent experiment [S. O. Valenzuela and M. Tinkham, Nature (London) 442, 176 (2006)], the authors present a quantitative microscopic theory to investigate the inverse spin-Hall effect with spin injection into aluminum considering both intrinsic and extrinsic spin-orbit couplings using the orthogonalized-plane-wave method.

Spin Hall effect, Hall effect, and spin precession in diffusive normal metals [PDF]
Physical Review B, 2005 We study transport in normal metals in an external magnetic field. This system exhibits an interplay between a transverse spin imbalance (spin Hall effect) caused by the spin-orbit interaction, a Hall effect via the Lorentz force, and spin precession due to the Zeeman effect. Diffusion equations for spin and charge flow are derived. The spin and charge

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.

Giant Room Temperature Interface Spin Hall and Inverse Spin Hall Effects [PDF]
Physical Review Letters, 2016 The spin Hall angle (SHA) is a measure of the efficiency with which a transverse spin current is generated from a charge current by the spin-orbit coupling and disorder in the spin Hall effect (SHE). In a study of the SHE for a Pt$|$Py (Py=Ni$_{80}$Fe$_{20}$) bilayer using a first-principles scattering approach, we find a SHA that increases ...

THEORY OF RESONANT SPIN HALL EFFECT [PDF]
International Journal of Modern Physics B, 2008 A brief review is presented on the resonant spin Hall effect, where a tiny external electric field induces a saturated spin Hall current in a 2-dimensional electron or hole gas in a perpendicular magnetic field. The phenomenon is attributed to the energy level crossing associated with the spin-orbit coupling and the Zeeman splitting.

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.

Crystalline Orientation–Dependent Spin Hall Effect in Epitaxial Platinum
Frontiers in Physics, 2022 We report on the spin Hall effect in epitaxial Pt films with well-defined crystalline (200), (220), and (111) orientations and smooth surfaces. The magnitude of the spin Hall effect has been determined by spin–torque ferromagnetic resonance measurements ...
