Résumé	We performed neutron spin echo measurements, on the geometrically frustrated antiferromagnet Y2Mo2O7 to reveal the magnetic nature of this glass-like system close to the freezing temperature, Tf. Diffuse magnetic scattering S(Q), indicative of spatial correlations, were observed to peak at a wave vector, Q≈0.45 Å−1 below 25 K. The normalized intermediate scattering function, , was measured as a function of temperature and Q. This provides evidence of the dynamics within the system and reveals at least two relaxation processes above and below Tf≈22.5 K.
