High-Efficiency Switching of the Topological Antiferromagnetic State in Mn3Sn via Magnon Torques.

Noncollinear antiferromagnet Mn3Sn offers a large anomalous Hall effect, zero stray field, and terahertz dynamics for high-density ultrafast memory, but switching its topological magnetic state remains challenging. Here, we demonstrate that magnon torques originating from Mn3Sn/NiO/W heterostructures can efficiently sw...
