Description:
Author(s): Marcin Matusiak, Krzysztof Rogacki, and Thomas Wolf Nematicity turns out to be a surprisingly common form of self-organization in strongly correlated electronic systems. Its presence along with superconductivity raises the question about a mutual relation between these two types of electronic order as well as about mechanisms that leads to their formation. Here, the authors show that the in-plane anisotropy of the Nernst effect (Δ ν / T ) in detwinned Ba(Fe 1 − x Co x ) 2 As 2 single crystals emerges at a temperature much higher than the temperature of the magnetic transition (TSDW). Furthermore, the temperature dependence of Δ ν / T retains its exponential character below and above TSDW, which suggests that the origin of nematicity might be something different from magnetic.
