Spin–Orbit Torque in Single-Molecule Junctions from ab Initio [PDF]
Journal of Chemical Theory and Computation, 2023 The use of electric fields applied across magnetic heterojunctions that lack spatial inversion symmetry has been previously proposed as a nonmagnetic means of controlling localized magnetic moments through spin–orbit torques (SOT).

Nonvolatile magnetization switching in a single-layer magnetic topological insulator
Communications 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.

Tunable spin-charge conversion through topological phase transitions in zigzag nanoribbons [PDF]
, 2016 We study spin-orbit torques and charge pumping in magnetic quasi-one dimensional zigzag nanoribbons with hexagonal lattice, in the presence of large intrinsic spin-orbit coupling. Such a system experiences topological phase transition from a trivial band

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
