Fig. 3: Modulation of effective magnetic damping by spin Hall effect in Mn₃Sn.

a Schematic image of modulation of magnetic damping torque τ^D by STT τ_STT due to conventional SHE in Mn₃Sn. The polar angle θ is fixed at 90°. b, c FMR line width δ at φ= −45°(b) and +135° (c) as a function of applied dc current.
