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)

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 ...

Spin-Orbit Torque Driven Multi-State Device for Memory Applications

, 2019
We report the design, fabrication and measurement of a spin-orbit torque (SOT) driven multi-state memory. The multi-state memory is based on a 3-nm thick Ni81Fe19 (Py) patterned in the shape of four intersecting ellipses (octagram).
