Abstract

In this paper an anisotropic exchange interaction is derived and separately fit to high- and low-frequency magnetic neutron scattering data of UPt3. This information is used to construct a superconducting pair potential in the strong spin-orbit coupling limit. Solutions of the gap equations show that both high- and low-frequency fluctuations support an A1u order parameter, which differ in their vector orientation. Implications of these results in relation to the unique phase diagram UPt3 will be discussed.
