a, b Theoretical calculation of the normalized nematic susceptibility χnem (a) and its inverse (b), plotted as a function of the relative temperature with respect to the theoretical nematic transition temperature (T − Tnem) for different spectral weight 0.7 ≤ Zxy ≤ 1. c, d Temperature dependence of c ∣2m66∣ and d \(| 2{m}_{66}-2{m}_{66}^{0}{| }^{-1}\) of optimally doped Fe1+yTe0.55Se0.45 (red circles) and BaFe2(As0.66P0.34)2 (black squares). The red and black lines show Curie–Weiss fittings. The data for BaFe2(As0.66P0.34)2 follows a Curie–Weiss behavior all the way up to 200K, whereas for Fe1+yTe0.55Se0.45, it deviates from Curie–Weiss behavior above ~50 K.
