Designed spin-texture-lattice to control anisotropic magnon transport in antiferromagnets

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Peter Meisenheimer, Maya Ramesh, Sajid Husain, Isaac Harris, Hyeon Woo Park | Summary: Spin waves in magnetic materials are promising information carriers for future computing technologies due to their ultra-low energy dissipation and long coherence length. Antiferromagnets are strong candidate materials due, in part, to their […]
