14. Although this is reminiscent of the behavior predicted for the thermal ferromagnetic transition by P. G. de Gennes and J. Friedel, J. Chem. Phys. Solids 4, 71 (1958) [see also M. E. Fisher and J. S. Langer, Phys. Rev. Lett. 20, 665 (1968)], the underlying physics is very different since our effect is entirely dynamical in origin.

18. This is because the spin-triplet interaction amplitude that enters perturbation theory for σ in the theory of disordered Fermi liquids [3] gets replaced by the paramagnon propagator in the case of an itinerant ferromagnet.

20. Certain logarithmic corrections were missed in Ref. [6]. References [7,8] show how they arise, and that the exact critical behavior is identical with that for an unidentified phase transition discussed before by T. R. Kirkpatrick and D. Belitz, Phys. Rev. B 45, 3187 (1992), identifying the transition treated in that paper as the ferromagnetic one.
