Anisotropy of the in-plane resistivity of underdoped Ba(Fe${}_{1-x}$Co${}_x$)${}_2$As${}_2$ superconductors induced by impurity scattering in the antiferromagnetic orthorhombic phase

We investigated the in-plane resistivity anisotropy for underdoped Ba(Fe${}_{1-x}$Co${}_x$)${}_2$As${}_2$ single crystals with improved quality. We demonstrate that the anisotropy in resis…
