The authors performed <sup>169</sup>Tm Mossbauer spectroscopy on the cubic Laves-phase compounds TmNi<sub>2</sub>, TmRh<sub>2</sub> and TmIr<sub>2</sub> in the temperature range 2-300K and found well resolved quadrupolar splitting at low temperature. In cubic compounds this feature is uncommon and they explain it as indicating the presence of a static or dynamic distortion. None of the three compounds investigated shows magnetic ordering at 2K or higher temperatures, nor can any of the three compounds be characterised as a van Vleck paramagnet at low temperatures.
