Abstract

Using inelastic scattering of polarized neutrons near a finite Bragg reflection, the dynamics of longitudinal S(q) q and transverse S(q) q spin fluctuations have been measured. The relaxation rates follow rather precisely the dipolar ynamic-scaling function calculated recently by mode-coupling theory based on the Lorentzian approximation. The predicted longitudinal line shape near TC disagrees with our data.
