Anisotropic in-plane resistivity and magnetoresistance of the detwinned BaFe2As2

We have measured the electrical resistivity and the magnetoresistance of detwinned BaFe2As2 single crystals in fields up to 16 Tesla. The temperature dependence of the resistivity shows a counterintuitive anisotropic behavior in the ab-plane, likely arising from the effect of the nematic susceptibility. Little magnetoresistance is observed at temperatures above the structural/magnetic transition, below which a huge in-plane magnetoresistance with an anisotropy is detected.
