- 論文の詳細を見る
We report a systematic investigation of Ba(Fe_<1-x>Co_x)_2As_2 based on transport and ^<75> As NMR measurements, and establish the electronic phase diagram. We demonstrate that doping progressively suppresses the uniform spin susceptibility and low frequency spin fluctuations. The optimum superconducting phase emerges at X_c≃0.08 when the tendency toward spin ordering completely diminishes. Our findings point toward the presence of a quantum critical point near x_c between the SDW (spin density wave) and superconducting phases.
