Abstract
An electron holographic method is introduced for the study of ferroelectric domain walls. The method allows not only direct imaging of the domain wall but also the measurement of local spontaneous polarization. Preliminary results of first high-resolution imaging of ferroelectric domain walls by using this technique in BaTiO3 and quantitative measurements of electrostatic field distribution across domain walls are presented.
