Ferroelectric domain configurations in a modified-PZT ceramic
TLDR
In this paper, the role of crystal imperfections in pinning the domain boundaries is discussed, and a modified-PZT ferroelectric ceramic which has rhombohedral symmetry is studied.Abstract:
Transmission electron microscopy and electron diffraction have been used to study ferroelectric domain configurations in a modified-PZT ferroelectric ceramic which has rhombohedral symmetry. Wedge-shaped domains with head-to-tail dipole arrangements and fine lamellar domains are most commonly observed. Switching between these domain types and various other domain configurations is interpreted, and the role of crystal imperfections in pinning the domain boundaries is discussed.read more

Electron Microscope Transmission Images of Coherent Domain Boundaries II. Observations
TL;DR: In this paper, a dynamic two-beam theory of domain fringes was developed and the properties of the fringe patterns, derived in part I, were observed and illustrated by means of examples, in particular, fringes resulting from ferroelectric domain-walls in barium titanate, and anti-ferromagnetic domain walls in nickel oxide.
