dc.descriptionThe authors of the Letter PRL 89, 017004 (2002) predict nontrivial flux lattice structures in UPt3 in vicinity of the superconducting transition between the A and B phases for low magnetic fields, an important conclusion for motivating future experiments. We show that the approach and the conclusions of this Letter are wrong. The transitions between the different superconducting phases in the mixed state are pointed out to be rather crossovers than real second-order phase transitions within the most popular theoretical models of a two-component superconducting order parameter for UPt3.
