Large out-of-plane spin–orbit torque in topological Weyl semimetal TaIrTe4

Nature Communications
The unique electronic properties of topological quantum materials, such as protected surface states and exotic quasiparticles, can provide an out-of-plane spin-polarized current needed for external field-free magnetization switching of magnets with ...

High write endurance up to 1012 cycles in a spin current-type magnetic memory array

AIP Advances, 2019
We demonstrated high write endurance of up to 1012 cycles with a pulse write current of 10 ns in a spin current-type (SC) single magnetic tunnel junction (MTJ) element and 8×8 memory array.

Efficiency of Spin-Transfer Torque-Assisted Spin-Orbit Torque Magnetization Switching Under In-Plane External Field Application [PDF]

We have simulated the magnetization dynamics under implementing spin-transfer torque (STT) and spin-orbit torque (SOT) simultaneously, which is regarded as the writing process of the next-generation 3-D domain wall magnetic memory (3D-DWMM).

Field-free spin–orbit torque switching in ferromagnetic trilayers at sub-ns timescales

Nature Communications
Current-induced spin torques enable the electrical control of the magnetization with low energy consumption. Conventional magnetic random access memory (MRAM) devices rely on spin-transfer torque (STT), this however limits MRAM applications because of ...

Effect of surface state hybridization on current-induced spin-orbit torque in thin topological insulator films

Scientific Reports, 2017
We investigate the thickness optimization for maximum current-induced spin-orbit torque (SOT) generated by topological surface states (TSS’s) in a bilayer system comprising of a ferromagnetic layer coupled to a thin topological insulator (TI) film.

Comparison of Current Induced Domain Wall Motion Driven by Spin Transfer Torque and by Spin Orbit Torque in Ferrimagnetic GdFeCo Wires

Magnetochemistry
Current-induced domain wall motion (CIDWM) in magnetic wires can be driven by spin transfer torque (STT) originating from transferring angular momentums of spin-polarized conducting electrons to the magnetic DW and can be driven by spin orbit torque (SOT)

Thermal spin–orbit torque with Dresselhaus spin–orbit coupling

Based on the spinor Boltzmann equation, we obtain a temperature-dependent thermal spin–orbit torque in terms of the local equilibrium distribution function in a two-dimensional ferromagnet with Dresselhaus spin–orbit coupling.

Effect of interfacial insertion layers on the spin-orbit torque in W(O)|CoFeB heterostructures

, 2019
We report on an experimental investigation of spin-orbit torque (SOT) in W(O)∣CoFeB heterostructures where a thin insertion layer with negligible spin-orbit coupling is inserted at the W(O)∣CoFeB interface.

Unconventional angular dependence of spin-orbit torque-induced harmonic Hall resistance in Pt/YIG bilayers

npj Spintronics
Spin-orbit torque (SOT), arising from spin-orbit coupling-induced spin currents, provides efficient control of magnetization. SOT characterization involving harmonic Hall resistances is typically done in low-current regimes, distinct from high-current ...
