The study of domain rearrangement under external electric fields by scanning electron acoustic microscope

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 BaTiO 3 ceramics induced by an external electric field were obtained. The results are discussed.
