    • Strictly speaking, our numerical results show not the genuine divergence of χ (Q) but a finite peak value of ∼6.28 μB /T because χ (Q) was calculated under a finite value of H (Q). In our numerical accuracy, the divergence of χ (Q) appears as the peak value larger than 6.2 μB /T.

    • Concerning the magnetic-field effect on the noncollinear feature, we also found that θ above the mean-field TN is almost field independent between under 0.1 and 3 T, while |〈M+〉| is nearly proportional to H (0) in this field range (not shown).

    • Around TN (or T*), 1/ T1 T is generally dominated by Imχ (qAF, ω0) / ω0, where qAF and ω0 represent the wave-number vector of AF order and the observing NMR frequency, respectively. Within the time-dependent Ginzburg-Landau equation, the sign of ∂/∂T χ (qAF, 0) and ∂/∂H χ (qAF, 0) agrees with, respectively, that of ∂/∂T Imχ (qAF, ω0) / ω0 and ∂/∂H Imχ (qAF, ω0) / ω0, as far as ω0 is lower enough than the characteristic relaxation frequency of the electron-spin dynamics. Thus it is likely that around TN (or T*), χ (qAF) and 1/ T1 T show the qualitatively similar temperature dependence and magnetic-field dependence.
