Flexible rotation of spontaneous polarization at ferroelectric domain walls is predicted in theory but lacks evidence from experiment. Here, Wei et al. image a Néel-like domain wall in Ti-rich ferroelectric Pb(Zr1−xTix)O3crystals, providing insight in exploring chiral domain walls in ferroelectrics.
