Deterministic Néel Vector Switching of Altermagnets Via Magnetic Octupole Torque
Researchers have demonstrated deterministic control of d‑d wave altermagnets by injecting a magnetic octupole current into an altermagnet/normal‑metal bilayer. The resulting magnetic octupole torque flips the Néel vector without any external magnetic field, converting inherently multidomain textures into a single‑domain state. Crucially, the process does not rely on net magnetization or the Dzyaloshinskii–Moriya interaction, broadening its applicability across diverse altermagnetic materials. This breakthrough paves the way for practical, field‑free spintronic components.
