Abstract
Currently, microscopic models based on spin-fluctuation-mediated pairing are at odds with phenomenological theories as regards the symmetry of the order parameter for the heavy-electron superconductor UPt3. The author shows that this discrepancy can be resolved for high-frequency spin fluctuations by including a weak ferromagnetic coupling between next-nearest-neighbor U atoms.
