Dichotomy between in-plane magnetic susceptibility and resistivity anisotropies in extremely strained BaFe2As2
Dichotomy between in-plane magnetic susceptibility and resistivity anisotropies in extremely strained BaFe2As2
The in-plane resistivity and uniform magnetic susceptibility anisotropies of $BaFe_{2}As_{2}$ are obtained with a new method, in which a large symmetry-breaking uniaxial strain is applied using a substrate with a very anisotropic thermal expansion. The resistivity anisotropy and its corresponding elastoresistivity exhibit very similar diverging behavior as those obtained from …
