Spin correlations in the pyrochlore antiferromagnet Y2Ru2O7 with Curie-Weiss temperature ΘCW* - 1100 K and critical temperature TN = 77 K were examined through neutron scattering. For TN < T < ΘCW / 3 the data show spin relaxation with a rate ℎΓ = 1.17(9)kBT. For T<TN spectral weight moves to higher energies with substantial changes up to 4kBTN. For T << TN there is a Δ = 11(1) meV energy gap and a pronounced spectral maximum at 19.7 meV. Throughout the temperature range examined, the wave vector dependence of inelastic scattering exhibits a broad peak for Qd ≈ 3.8 (d is the Ru-Ru spacing) consistent with dipolar spin correlations
