Asymmetric Spin Torque Unlocks Deterministic Control of Antiferromagnetic Memory (IMAGE)
Caption
Schematic illustrations of the physical mechanism underlying asymmetric spin torque in antiferromagnetic systems. At the interface of thin films or devices, symmetry reduction results in unequal absorption of the injected spin current by the A and B sublattices of the antiferromagnet, thereby generating an asymmetric spin torque that drives deterministic switching of the Néel vector.
