Using broadband microwave spectroscopy on thin-film samples of the heavy-fermion materials UPd 2 Al 3 and UNi 2 Al 3 , we find that the frequency-dependent conductivity of these compounds at low temperatures follows a simple Drude prediction. The observed relaxation rates in the GHz frequency range are extremely low for a metal.
