Structural diffuse scattering in nominally stoichiometric Yb2Ti2O7. a The diffuse neutron scattering from the as-grown, nominally stoichiometric sample measured at T ~ 30 K in the (hk7) plane contains weaker structural scattering resembling the scattering from the oxygen-deficient sample. b The same crystal measured after annealing in oxygen, showing that most of the diffuse scattering has been eliminated. The remaining scattering is attributed to inelastic scattering from phonons, see Supplementary Figure 1. c 1D cuts along [h,4,6.8] for the oxygen-depleted, as-grown and oxygen-annealed samples. This cut was chosen to minimise inelastic scattering. The broad structural diffuse features at h ~ ±4 are clearly present for the oxygen-depleted and as-grown samples, but are greatly reduced for the oxygen-annealed sample
