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.
