文摘We have studied the domain configurations and structures of KNbO_(3) crystal in orthorhombic and tetragonal phases by polarizing microscopy.The phase transition processes among orthorhombic,tetragonal and cubic phases and thermal hysteresis during phase transitions are observed directly.Domain-pattern changes and the stable domain patterns during the phase transitions are discussed.
