Anisotropic impurity states, quasiparticle scattering and nematic transport in underdoped Ca(Fe1−xCox)2As2
Iron-based high-temperature superconductivity develops when the 'parent'antiferromagnetic/
orthorhombic phase is suppressed, typically by introduction of dopant atoms. But their …

Anisotropic in-plane resistivity in the nematic phase of the iron pnictides
RM Fernandes, E Abrahams, J Schmalian - Physical review letters, 2011 - APS
We show that the interference between scattering by impurities and by critical spin
fluctuations gives rise to anisotropic transport in the Ising-nematic state of the iron pnictides …
