a Temperature and doping dependence of nematic fluctuations in the B1g channel, with elastoresistivity coefficient m11 − m12, and b B2g channel, with 2m66. For clarity, the elastoresistivity data for each doping are offset by 15 and 20 in a, b, respectively. c–e Temperature dependence of c m11 − m12 for x = 0, d 2m66 for x = 0.45 and e −2m66 for Ba(Fe0.93Co0.07)2As2. Lower panels show the inverse. Solid black curves are Curie–Weiss fits. The optimal fitting range is determined by the greatest corresponding adjusted R-square value (see Supplementary Note 4). Shaded gray regions indicate the range of temperatures where the elastoresistivity coefficients follow a Curie–Weiss law.
