[en] The temperature dependent spin dynamics of vanadium impurities in the Kondo alloy AuV (theta/sub K/ approximately equal to 300K) have been studied by means of measurements of ⁵¹V transverse relaxation rates (T₂^-1) for the temperature range 1 to 260 K and vanadium concentrations of 0.2 and 0.5 at.%. Contrary to published reports, we find the quantity T₂T to increase markedly with increasing temperature. Its magnitude at 260 K [15(+-5) msec-K] exceeds the limiting low-temperature value by a factor of 10. The observed increase in T₂T indicates a large reduction in the impurity spin-correlation time, e.g., tau/sub e/(theta/sub K/)/tau/sub e/(0) approximately equal to 0.2
