The thermal conductivity $̨appa$ and thermopower S in the heavy-fermion alloy CeCu6-xAux at the critical concentration x=0.1 separating magnetically ordered and non-magnetic ground states, has been measured in the range 0.1\textendash{}2.5K at zero magnetic field and B=6T. $̨appa$(T) is found to be linear at high T in close agreement with pure CeCu6. In the limit of low T, $̨appa$ is strongly suppressed. In contrast to x=0, for x=0.1$̨appa$ increases only very weakly in a magnetic field of 6T. The (positive) thermopower is enhanced with respect to x=0, dropping off only well below 0.5K. The magnetic field reduces strongly the value of S and leads to a collapse of S(T) for x=0 and 0.1 onto identical curves.     «
