Abstract
The dV/dI(V) characteristics of point contacts on single crystals of UPd2Al 3 and UNi2Al3 were measured in the temperature range 1.6-30 K. The dV/dI of UPd2Al3 contacts reveal distinct peculiarities related to the antiferromag netic ordering, contrary to UNi2Al3 point contacts. Spectral features manif esting a partially gapped Fermi surface in the antiferromagnetic state were not observed in the dV/dI curves. (C) 1999 Elsevier Science B.V. Ail right s reserved.
