Abstract
Electronic relaxation in rare earth materials has been a subject of considerable interest in recent years. Several metallic thulium compounds, Tm, TmAl, TmCu, and TmxY1-xCu, were studied using Mössbauer spectroscopy over the temperature range of 65 mK to T > TNéel. All of the spectra can be well described by including electronic relaxation using the matrix formalism of L. L. Hirst. The general features of the spectra for all these materials are similar, even though Tm is hexagonal and shows a complex spin structure in neutron diffraction studies, TmAl is orthorhombic, and TmCu and TmxY1-xCu are cubic.
