Two-axis neutron-scattering measurements on a 1 μm thick holmium film reveal the presence of two magnetic correlation lengths above T N 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 line-shape with widths that, for temperatures sufficiently close to T N , differ by a factor of ten or more.
