✦ Synopsis

The author observed that information inferred from current interpretations of experimental data for the heavy, electron superconductor UPh constrain the order parameter to be of Ez. symmetry. Possible objections to the current interpretations will be given.

The tetracritical point seen in the H-T phase diagram of UPt3 for several orientations of H strongly constrains Ginzburg-Landau (GL) theories, as the GL "Hamiltonian" must have a conserved quantity Q. A two-component vector order parameter model has a Q for HNc , but no tetracritical point. Among ac
