continuously disordered ground state. Neutron powder diffraction experiments have
detected magnetic scattering similar in form to a liquid structure factor. We present a single
crystal neutron scattering study of the pyrochlore CsNiCrF 6 and quantify the anisotropy of
the scattering. Using these data, we show that there are strong correlations between nearest-
neighbor spins, and no significant longer correlations. This provides clear evidence for the …
