—vŽ|    We will report the discovery of superconductivity in SmFeAsO1-xFx with Tc higher than 40 K in Fe-based superconductors, and give a brief review on the properties of the material.
   We show the transport properties (resistivity, Hall coefficient, TEP) in the normal state. The results suggest a quantum phase transition around x=0.14 in SmFeAsO1-xFx system. An electronic phase diagram is proposed.
   In addition, the anisotropy in resistivity and susceptibility is also discussed in single crystals BaFe2As2 and CaFe2As2. The phase diagrams of Ba1-xKxFe2As2 and BaFe2-xCoxAs2 system and isotope effect are also discussed.
