abstract = {In contrast to the flexible rotation of magnetization
direction in ferromagnets, the spontaneous polarization in
ferroelectric materials is highly confined along the
symmetry-allowed directions. Accordingly, chirality at
ferroelectric domain walls was treated only at the
theoretical level and its real appearance is still a
mystery. Here we report a Néel-like domain wall imaged by
atom-resolved transmission electron microscopy in Ti-rich
ferroelectric Pb(Zr1−xTix)O3 crystals, where
nanometre-scale monoclinic order coexists with the
tetragonal order. The formation of such domain walls is
interpreted in the light of polarization discontinuity and
clamping effects at phase boundaries between the nesting
domains. Phase-field simulation confirms that the
coexistence of both phases as encountered near the
morphotropic phase boundary promotes the polarization to
rotate in a continuous manner. Our results provide a further
insight into the complex domain configuration in
ferroelectrics, and establish a foundation towards exploring
chiral domain walls in ferroelectrics.},
