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)

Topological spin-orbit torque in ferrimagnetic Weyl semimetal

Physical Review Research
We theoretically find a topological spin-orbit torque (SOT) in the compensated ferrimagnetic Weyl semimetal Ti_{2}MnAl. The topological SOT arises from all the occupied states, which is free from dissipation. However, it is negligible in metallic magnets
