Av. Ulinzheev et al., PHASE-TRANSITIONS INDUCED IN NANBO3 CRYSTALS BY VARYING THE DIRECTIONOF AN EXTERNAL ELECTRIC-FIELD, Physics of the solid state, 39(6), 1997, pp. 972-974
The anisotropic behavior of the electrostatic held characterizing the
phase transition from an antiferroelectric state to a ferroelectric st
ate is studied for the first time with NaNbO3 as an example. Structura
l changes taking place in the crystal as the direction of the electros
tatic field is varied are studied and electrostatic field magnitude-di
rection phase diagrams are determined. (C) 1997 American Institute of
