Spin-orbit torques originating from the bulk and interface in Pt-based structures

open access: yesPhysical Review Research, 2021
We investigate spin-orbit torques in prototypical Pt-based spintronic devices. We find that, in Pt/Ni and Pt/Fe bilayers, the dampinglike torque efficiency depends on the thickness of the Pt layer.

Magnetization switching driven by current-induced torque from weakly spin-orbit coupled Zr

open access: yesPhysical Review Research, 2020
Current-induced magnetization switching (CIMS) via the spin-orbit torque is technologically important for applications of spintronic devices. Existing experimental studies are focused on 5d heavy metals with large spin-orbit coupling but theoretical ...

Strong variation of spin-orbit torques with relative spin relaxation rates in ferrimagnets

open access: yesNature Communications, 2023
There has been a lot of interest in using antiferromagnets for magnetic memories, due to their fast dynamics, and resilience to stray fields. Such a memory was supposed to be switched by a spin-orbit torque. Here, Zhu and Ralph find that as a ferrimagnet

Hidden interplay of current-induced spin and orbital torques in bulk Fe_{3}GeTe_{2}

open access: yesPhysical Review Research, 2022
Low crystal symmetry of magnetic van der Waals materials naturally promotes spin-orbital complexity unachievable in common magnetic materials used for spin-orbit torque switching.

Nonvolatile magnetization switching in a single-layer magnetic topological insulator

open access: yesCommunications Physics, 2023
Magnetization in a ferromagnetic layer could be manipulated by the spin-orbit torque whose generation commonly relies on the spin-orbit coupling from the adjacent heavy-metal layer within the bilayer.

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

open access: yesNature 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

open access: yesAIP 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

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

open access: yesNature 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

open access: yesAPL 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.
