Unusual superconducting state at 49 K in electron-doped CaFe(2)As(2) at ambient pressure

We report the detection of unusual superconductivity up to 49 K in single crystalline CaFe(2)As(2) via electron-doping by partial replacement of Ca by rare-earth. The superconducting transition observed suggests the possible existence of two phases: one starting at 49 K, which has a low critical fie...
