Abstract:Keywords: ferroelectrics, in situ powder diffraction, domain switchingThe origin of the extremely high piezoelectric response of morphotropic ferroelectric lead zirconate titanate (PZT), PbZr (1-x) Ti (x) O 3 , is still under discussion. Noheda et al. [1] proposed a monoclinic phase at the morphotropic phase boundary (MPB) as an explanation, via which a rotation of the polarization direction is possible. However, interpretation of X-ray data so far has not taken into account the strongly varying domain stru… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
