Abstract

The experimental electron-density distribution of ferroelectric bismuth ferrite (BiFeO3) has been visualized using the synchrotron X-ray powder diffraction data and the maximum-entropy method. The present work has clearly revealed the partial covalency of the Bi-O bond, which is a key to understand the spontaneous polarization. Density functional theory (DFT) calculation has supported the validity of the experimental results.
