Inhaltszusammenfassung
The node structure of the superconducting order parameter of the heavy-fermion system UPd2Al3 is analyzed within the weak-coupling theory. A pairing interaction induced by the exchange of antiferromagnetic spin excitations is assumed as suggested by recent inelastic neutron scattering experiments and tunneling spectroscopy. The multi-sheeted Fermi surface is taken into account. Based on a model susceptibility for the simple antiferromagnetic structure of UPd2Al3, line nodes result at the ...The node structure of the superconducting order parameter of the heavy-fermion system UPd2Al3 is analyzed within the weak-coupling theory.
