　　In this talk, I will show that the atomic scale polarization map in ferroelectrics can be determined using aberration-corrected TEM images owing to the large atomic displacements responsible for the dipole moment.This study reveals how interfaces in complex multidomain geometries lead to the formation of polarization vortices with electric flux closure domains [1].
