A simple formula describing the influence of the crystalline electric field free‐ion excitations on the temperature dependence of the contribution of the s–f scattering to the thermal resistivity of normal rare‐earth metals is presented. The corresponding formula for the electrical resistivity is also given and compared to the one being currently used. Theoretical electron–phonon scattering contributions derived in earlier papers and constant impurity scattering contributions are added to the derived s–f contribution formulae in order to fit the total electrical and thermal resistivity represented as functions of the temperature to experimental dependences on the temperature for DyIn3 and in this way to manifest applicability of the derived formulae to real materials.
