Critical spin fluctuations and the origin of nematic order in Ba(Fe sub(1-x)Co sub(x)) sub(2)As sub(2)

Nematic fluctuations and order play a prominent role in material classes such as the cuprates, some ruthenates or the iron-based compounds and may be interrelated with superconductivity. In iron-based compounds signatures of nematicity have been observed in a variety of experiments. However, the fun...
