- 論文の詳細を見る
The mechanism of incommensurate (IC) spin-density-wave (SDW) order observed in the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) phase of CeCoIn_5 is discussed on the basis of new mode-coupling scheme among IC-SDW order, two superconducting orders of FFLO with B_<1g> (d_<x^2-y^2>) symmetry and π-pairing of odd-parity. Unlike the mode-coupling schemes proposed quite recently by Kenzelmann et al., that proposed in the present Letter can offer a simple explanation for why the IC-SDW order is observed only in FFLO phase and the IC wave vector is rather robust against the magnetic field.
