CaMn${}_2$Sb${}_2$: Spin waves on a frustrated antiferromagnetic honeycomb lattice

D. E. McNally, J. W. Simonson, J. J. Kistner-Morris +6

We present inelastic neutron scattering measurements of the antiferromagnetic insulator CaMn${}_2$Sb${}_2$, which consists of corrugated honeycomb layers of Mn. The dispersion of magne…
