摘要：

When the sintered BaTiO3 specimens were treated at 200-degrees-C and cooled under compressive stress, notable change in domain configuration occurred. As a result of external compressive stress applied during transformation from cubic to tetragonal, the banded domain structure has changed to a simple lamellar one and the 90-degrees domains have aligned. The observed change in domain configuration under external stress has been explained in terms of elastic strain energy minimization.
