✦ Synopsis
Two-axis neutron-scattering measurements on a l /am thick holmium film reveal the presence of two magnetic correlation lengths above TN that are qualitatively similar to those recently observed in X-ray and neutron scattering studies of bulk holmium and terbium. The scattering profile is well described by a broad Lorentzian plus a narrow Lorentzian-squared lineshape with widths that, for temperatures sufficiently close to TN, differ by a factor of ten or more.
