Fig. 3: Phase diagram of Ba(Fe1−xCox)2As2.
From: Quantum critical fluctuations in an Fe-based superconductor
The spin-density-wave (SDW) phase is depicted in gray, nematicity in red, and superconductivity (SC) in blue as defined by the superconducting transition temperature Tc. The rectangular and circular data points indicate the crossover temperatures \({T}_{{{{{{{{\rm{UD}}}}}}}}}^{* }\) and \({T}_{{{{{{{{\rm{OD}}}}}}}}}^{* }\) from the region of Ω/T scaling for x < xc and x > xc, respectively. The dashed lines are guides to the eye. Open red squares and circles represent data points from Lederer et al.29. The gray, red, and blue phase separation lines are based on Chu et al.19. The error bars indicate the temperature window of T* depicted in Fig. 2.
