Non-Reciprocal Zone Boundary Magnon Propagation in Cu${}_2$OSeO${}_3$

Tobias Weber, Niclas Heinsdorf, Michal Stekiel +3

Inelastic neutron scattering in the chiral magnet Cu${}_2$OSeO${}_3$ reveals strong non-reciprocal effects on magnon propagation at the boundary of the nuclear Brillouin zone. The non-…
