Setting of the magnetic structure of chiral kagome antiferromagnets by a seeded spin-orbit torque

Science Advances, 2022
The current-induced spin-orbit torque switching of ferromagnets has had huge impact in spintronics. However, short spin-diffusion lengths limit the thickness of switchable ferromagnetic layers, thereby limiting their thermal stability.

Robust spin-orbit torque and spin-galvanic effect at the Fe/GaAs (001) interface at room temperature

Nature Communications, 2016
Interfacial spin-orbit torque allows electrical manipulation of magnetization, but this has been shown mostly in polycrystalline metal bilayers. Here the authors show robust spin-orbit torque in single crystalline Fe/GaAs interface at room temperature ...

Spin torque on the surface of graphene in the presence of spin orbit splitting

AIP Advances, 2013
We study theoretically the spin transfer torque of a ferromagnetic layer coupled to (deposited onto) a graphene surface in the presence of the Rashba spin orbit coupling (RSOC). We show that the RSOC induces an effective magnetic field, which will result

Giant bulk spin–orbit torque and efficient electrical switching in single ferrimagnetic FeTb layers with strong perpendicular magnetic anisotropy [PDF]

Applied Physics Reviews, 2022
Efficient manipulation of antiferromagnetically coupled materials that are integration-friendly and have strong perpendicular magnetic anisotropy (PMA) is of great interest for low-power, fast, dense magnetic storage and computing.

Generation of coherent spin-wave modes in yttrium iron garnet microdiscs by spin–orbit torque

Nature Communications, 2016
Spin-orbit interactions allow for pure spin current to be injected into a ferromagnetic insulator from a current-carrying heavy metal, generating torque on the magnetization.

Field-free magnetization switching induced by the unconventional spin–orbit torque from WTe2

APL Materials, 2021
Spin–orbit torque provides a highly efficient way to achieve current-induced magnetization switching, which relies on charge-to-spin conversion of the spin source layer.
