| 中文摘要 | As-75 nuclear magnetic resonance (NMR) was measured for Ba(Fe1-xNix)(2)As-2 single crystals with x = 0.05 and x = 0.1 under 0 and 1.5 GPa, respectively. For the optimal doped sample with x = 0.05, the superconducting transition temperature, T-c, is strongly suppressed from 18 to 5 K, while for the over-doped sample with x = 0.1, it is turned from a superconducting ground state to a disordered paramagnetic state under 1.5 GPa. Our experimental results show that the antiferromagnetic spin fluctuations, as well as T-c, are suppressed. The experimental results can be explained with the two-band model. As a result, the electronic band is shifted downwards with an increase in pressure, and the electrons become the dominant carriers in the system. |
