Abstract
Recent results of superconducting tunneling spectroscopy on epitaxial thin films of the antiferromagnetic heavy-fermion superconductor UPd2Al3, are pr esented. Strong-coupling effects in the tunneling density of stales are ana lyzed within the framework of the anisotropic Eliashberg theory for a pair- coupling mechanism based on the exchange of antiferromagnetic spin excitati ons. The multi-sheeted Fermi surface of UPd2Al3 is taken into account. (C) 2000 Elsevier Science B.V. All rights reserved.
