Low energy magnons in the chiral ferrimagnet ${\text{Cu}}_2{\text{OSeO}}_3$: a coarse-grained approach

Yi Luo, G. G. Marcus, B. A. Trump +7

We report a comprehensive neutron scattering study of low energy magnetic excitations in the breathing pyrochlore helimagnetic ${\text{Cu}}_2{\text{OSeO}}_3$. Fully documenting the fou…
