dc.description.abstract	The photoinduced reflectivity change of optimally doped BaFe1.87Co0.13As2 is investigated. It is observed that the nematic signal in the photoinduced reflectivity change continues to increase as temperature decreases, reflecting its fluctuating nature. However, fluence-dependent measurements show saturation of the nematic signal at higher pump fluence, a typical behavior of a static order parameter. Temperature-dependent evolution of the saturation and the characteristic relaxation time of the nematic signal suggest that the nematicity of a spin and/or orbital origin develops at lower temperature on top of the nematicity coupled to the lattice that dominates the higher temperature nematic response. © 2020 WILEY-VCH Verlag GmbH & Co.
