Abstract
Phase stability of (1 − x) (Bi1/2Na1/2)TiO3-x BaTiO3 (0 ≤ x ≤ 0.15) under electric field was investigated by measuring volume changes during a bipolar poling cycle. The unique nature of field-dependent phase stability with three distinctive regions is revealed by comparative studies using commercial soft PZT and relaxor PLZT. For x ≤ 0.06 and x ≥ 0.13, similarly with PZT and PLZT, the axial strain expands with the contracting radial strain, but the former results in a remanent volume demonstrating an electric-field-induced phase transition. For 0.08 ≤ x ≤ 0.12, this field-induced phase transition is distinguished by negligible radial contractions implying polarization rotation. A “poling-induced” morphotropic phase boundary forms at x = 0.07.
