Octupole-driven spin torque switching of antiferromagnetic tunnel junctions

Nature, Published online: 21 October 2026; doi:10.1038/s41586-026-11172-5 All-antiferromagnetic tunnel junctions can display both a large TMR and a reciprocal switching effect, octupole-driven spin-transfer torque, enabling nanoscale magnetic memory and potentially room-temperature terahertz…
