Abstract
Compared with other methods, scanning electron acoustic microscope (SEAM) is a convenient, fast and nondestructive technique revealing ferroelectric domain without any special pre-treatment to the sample. It is also a promising technique for the dynamic study of domain structure of ferroelectric materials. In the initial research, detailed images of rearrangement of domains in BaTiO3 ceramics induced by an external electric field were obtained. The results are discussed.
