Spin-wave dynamics in the KCeS2 delafossite: A theoretical description of powder inelastic neutron-scattering data

S. M. Avdoshenko, A. A. Kulbakov, E. Häußler +4

Layered rare-earth delafossites $AR{X}_2$ with $R$ = Yb(III) or Ce(III) have received a lot of interest as potential hosts for a quantum spin-liquid ground state. Some systems of thi…
