Deterministic Switching of Perpendicular Ferromagnets by Higher harmonics of Spin-orbit Torque in Noncentrosymmetric Weyl Semimetals

Fei Xue, Naomi Fokkens

Higher angular harmonics of spin-orbit torques enable deterministic switching of perpendicular ferromagnets even when in-plane mirror symmetries are preserved.

✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

deterministic switching can instead be achieved through higher angular harmonics of spin-orbit torques, even in systems that preserve in-plane mirror symmetries.

C2weakest assumption

That the higher-harmonic torque components reach magnitudes comparable to the conventional lowest-order torques in the chosen material.

C3one line summary

Higher-harmonic components of spin-orbit torque in Weyl ferromagnets enable deterministic magnetization reversal without external fields or additional symmetry breaking.
