Electric-field-induced non-ergodic relaxor to ferroelectric transition in BiFeO₃-xSrTiO₃ ceramics.

ABSTRACT: While BiFeO₃-based solid solutions show great promise for applications in energy conversion and storage, realizing this promise necessitates understanding the structure-property relationship in particular pertaining to the relaxor-like characteristics often exhibited by solid solutions with polar-to-non-polar morphotropic phase boundaries. To this end, we investigated the role of the compositionally-driven relaxor state in (100 - x)BiFeO₃-xSrTiO₃ [BFO-xSTO], via in situ synchrotron X-ray diffraction under bipolar electric-field cycling. The electric-field induced changes to the crystal structure, phase fraction and domain textures were monitored via the {111}_pc, {200}_pc, and 1/2{311}_pc Brag
