报告摘要：We will talk about the discovery of superconductivity with Tc higher than 40 K in Fe-based compounds. In this talk, we will present the transport properties (resistivity, Hall coefficient, thermopower) in the normal state of these superconductors. These results suggest a quantum critical point around doping level x = 0.14 in the SmFeAsO1-xFx system. An electronic phase diagram is proposed. We will also discuss the anisotropy in resistivity and susceptibility in the recently discovered BaFe2As2 and CaFe2As2 single crystals.
