    Optical investigation of the electrodynamic response of UPd2Al3
    (1994) Degiorgi, Leonardo E.; Dressel, Martin; Grüner, George; Wachter, Peter; Sato, Noriaki; Komatsubara, Takemi
    We have investigated the electrodynamic response of UPd2Al3 both above and below the antiferromagnetic phase transition at TN = 14 K. At low temperatures, we observe the formation of a low-frequency narrow resonance, which indicates the development of the many-body coherent state. However, we do not fmd any evidence of a gap absorption associated with a spin-density-wave state, which would develop if the state arised as a consequence of a Fermi surface instability.
