CsNiCrF6: a potential quantum spin liquid observed by the muon’s additional decoherence due to multiple Coulomb phases?

CsNiCrF6 is a material which exhibits multiple Coulomb phases: spin ice, charge ice, and displacement ice. We have previously carried out an investigation on this experiment with MuSR in Cycle 23/3, and we found evidence of an F--µ--F oscillation which is heavily damped, and we expect the origin of this damping to be due to the dynamics in the electronic moments. We attempted to decouple the electronic dynamics by applying a series of longitudinal fields, but we could not do this with MuSR. Therefore, we wish to run the sample on HiFi to attempt to decouple the dynamics and observe the way in which the muon-spin relaxation rate changes.
