Dipolar spin ice states with fast monopole hopping rate in CdEr${}_2$X${}_4$ (X = Se, S)

Shang Gao, Oksana Zaharko, Vladimir Tsurkan +19

Excitations in a spin ice behave as magnetic monopoles, and their population and mobility control the dynamics of a spin ice at low temperature. CdEr${}_2$Se${}_4$ is reported to have…
