Summary

This work demonstrates quantum imaging of spin-orbit torque dynamics in an all-vdW heterostructure.

My contribution

I separated field-like and damping-like torque contributions and analyzed the critical current densities required for deterministic switching, clarifying the SOT and STT interplay in the Fe3GaTe2 and hBN system.
