Abstract

A phenomenological free energy which includes a novel coupling between vector superconducting and magnetic order parameters is deduced for ${UPt}_{3}$ . Analysis of this free energy leads to a phase diagram in the H-T plane in agreement with experiment, and identifies the symmetry of the different phases. Some further experiments are suggested.
