The temperature dependence of the $^{73}$Ge nuclear-spin-lattice-relaxation rate $1/T_1$ indicates the development of magnetic correlations and the formation of a Fermi-liquid state at temperatures lower than $T_{\\rm FL}=0.4$ K, where $1/T_1T$ is constant. The resistance and $1/T_1T$ measured on an as-grown sample decrease below $T_{\\rm c}^{\\rm onset} = 0.2$ K and $T_{\\rm c}^{\\rm NQR} = 0.1$ K, respectively; these are indicative of the onset of superconductivity.
