ABSTRACT
Domain-switching in BaTiO3 single crystal under an antiparallel electric field was investigated in this paper by polarized light microscope. It was found that 180° domain-switching consisted of two 90° switching steps. The polarization reversal of domains took place when an antiparallel electric field was applied to the BaTiO3 single crystal. The domain-switching process was different under different field intensities. Under a low field, all domains switched 180° through two 90° domain-switching steps. However, under a high field, only some 90° domains were nucleated in the initial period and subsequently all domains switched to the direction of the external field quickly.
