In the recent letter [1] by H. Ikeda and Y. Ohashi, a new, very attractive idea is proposed for the explanation of the micromagnetism in U-based heavy fermion compounds. For this sake a nontrivial spin density wave (d-SDW) is introduced. Our goal is to claim, that in the model considered, the mean-field analysis is incomplete: the ferromagnetic state missed by [1] overcomes d-SDW in a large region of the phase diagram (Fig.1 in [1]).

Itinerancy and hidden order in URu2Si2
We argue that key characteristics of the enigmatic transition at T0 = 17.5 K in URu2Si2 indicate that the hidden order is a density wave formed within a band of composite quasiparticles, whose…

There is no true transition to a state with long range order in a 2D system with a continuous symmetry except for T =0
    For simpicity we use the random phase approximation
      There is not any unconventional SDW state for J ≤ 0
        SDW is more favorable among all other SDW (extended s-and p-states) due to the Van Hove singularity
