Ba（Fe1-xNix）2As 2中~（75）As NMR与H0 { \perp } c轴的局部磁不均匀性
Local magnetic inhomogeneities observed via 75As NMR in Ba(Fe1-xNix)2As2 with H0 {\perp} c-axis
摘要：
本文报道了Ba（Fe_（1-x）Ni_x）_2As_2（x=0.0072）自旋密度波（SDW）态的~（75）As核磁共振（NMR）测量结果。大的单晶与垂直于c轴的外场H 0对齐。光谱作为掺杂的函数被越来越宽，并且与具有局部杂质的相称SDW的模型很好地拟合。
英文摘要：
We present field-swept 75As Nuclear Magnetic Resonance (NMR) measurements in the spin-density wave (SDW) state of Ba(Fe1-xNix)2As2 for x=0.0072. The large single crystals were aligned with the external field H0 perpendicular to the c axis. The spectra are increasingly broadened as a function of doping, and are well fit by a model of a commensurate SDW with local impurities.
