Arushanov, S. Levcenko, G. Fuchs, B. Holzapfel, S. Drechsler, L. Schultz] We show that the temperature-dependent resistivity ρ(T), Hall number n H(T) and the cotangent of the Hall angle cot θ H(T) of Ba(Fe1−x Cox)As2 (x=0.0-0.2) can be scaled using a recently proposed model-independent scaling method (Luo et al. in Phys. Rev. B 77:014529, 2008). The zero field normal-state resistivity above T c can be reproduced by the expresion $\rho(T) = \rho_{0} +cT\exp(- \frac{2\varDelta }{T} )$ and scaled using the energy scale Δ, c and the residual resistivity ρ 0 as scaling parameters. The scaling parameters have been calculated and the compositional variation of 2Δ and ρ 0 has been determined. The 2Δ(x) dependence show almost linear decreasing in underdoped regime, minimum corresponding to the T c maximum and increasing in overdoped regime. The latter is different from that reported for cuprates. The existence of a universal metallic ρ(T) curve which, however, is restricted for the underdoped compounds to temperatures above a structural and antiferromagnetic transition is interpreted as an indication of a single mechanism which dominates the scattering of the charge carriers in Ba(Fe1−x Cox)As2 (x=0.0-0.2).
