The thermal conductivity of gadolinium monosulphidc was measured within the temperature range of 80 to 720 °K. The lattice part of the thermal conductivity (X L ) mas determined. It is difficult to explain the temperature dependence of x L , theoretically taking the phonon scattering by conduction clcctrons into account contrary to the case of the lanthanum monochalcogenides. The additional lattice thermal resistivity in GdS is attributed to phonon scattering on the paramagnetic statcs of Gd ions in the crystal field.
