M. Takashige et al., AFM OBSERVATION OF 90-DEGREES DOMAINS OF BATIO3 UNDER APPLICATION OF AN ELECTRIC-FIELD, Journal of the Physical Society of Japan, 66(8), 1997, pp. 2272-2275
The 90 degrees domains in tetragonal barium titanate BaTiO3 have been
observed with atomic force microscopy (AFM) under application of an el
ectric field. The nucleation and growth of a wedge-shaped c-domain and
the movement of the 90 degrees domain boundary were observed.
