摘要：

We report on the observation of a pseudogap at low temperatures in the heavy fermion compound UPt3, together with a renormalized low frequency Drude response. The gap energy, in units of (h) over bar omega/k(B), is comparable to the temperature where the magnetic correlations develop, 5 K, and the pseudogap progressively disappears above this temperature.
