Transport properties of Ni-doped BaFe 2Γx Ni x As 2 single crystals have been investigated and the electronic phase diagram is derived. T c reaches 20 K at the optimal doping level x ΒΌ 0:10. There is a small doping range around x ΒΌ 0:055 where superconductivity and spin-density wave order coexist. T
