The (weak) X-ray resonant magnetic scattering that appears near the ordering temperature (T(N) = 172 K) has been measured, giving information on the magnetic correlations that appear above T(N). The intensities of the resonant scattering are sufficient to measure this scattering. Moreover, the resolution available with synchrotrons is superior to that available with neutrons, so that it is interesting to compare the results from X-ray and neutron experiments. Quite different profiles are seen in the two experiments. The X-ray experiments observe a component above T(N) in the critical regime that suggests a much longer correlation length than is observed in the neutron experiments.
