For small Au concentrations $0 \\leq x < 0.16$, the compound undergoes a structural transition from orthorhombic to monoclinic crystal symmetry at a temperature $T_{s}$ with $T_{s} \\rightarrow 0$ for $x \\approx 0.15$. Antiferromagnetic order sets in close to $x \\approx 0.1$. To shed light on the interplay between quantum critical magnetic and structural fluctuations we performed neutron-scattering and thermodynamic measurements on samples with $0 \\leq x\\leq 0.3$.
