(a) Temperature dependence of the resistivity of the Ba1−xKxFe2As2 single crystals with different doping levels. Inset: Zoom into the temperature range close Tc. (b) The resistivity versus squared temperature. Dashed curves are the fits using ρ(T) = ρ0 + AFLT2. Inset: Doping dependence of the AFL coefficient. The data for x = 1 are taken from Ref. 46.
