Description:
Author(s): Chao Ma, Lijun Wu, Wei-Guo Yin, Huaixin Yang, Honglong Shi, Zhiwei Wang, Jianqi Li, C. C. Homes, and Yimei Zhu We use a quantitative convergent beam electron diffraction based method to image the valence electron density distribution in Ba(Fe1−xCox)2As2. We show a remarkable increase in both the charge quadrupole of the Fe cations and the charge dipole of the arsenic anions upon Co doping from x=0 (Tc=0 K) ... [Phys. Rev.
