| Abstract: | Two representative superconductors, UPt3 and Sr2RuO4, are comparatively studied on the basis of a general symmetry argument. The existing experimental data set for both systems strongly and commonly points to a triplet pairing. For the former, heavy fermion material, UPt3, a non-unitary bipolar state is the most possible candidate, whereas for the latter system, Sr2RuO4, determination of a precise pairing symmetry class, either unitary or non-unitary, is debated. |
