Effect of mechanical depoling on piezoelectric properties of Na0.5Bi0.5TiO3 - xBaTiO3 in the morphotropic phase boundary region
Denis, L; Glaum, Julia; Hoffman, Mark; Daniels, John E.; Hooper, Ryan; Tutuncu, Goknur; Forrester, Jennifer; Jones, Jacob L. (Journal article; Peer reviewed, 2018)The effect of mechanical stress on the direct piezoelectric properties of pre-poled (1 − x)(Na0.5Bi0.5)TiO3–xBaTiO3 (NBT–xBT) in the range 4% ≤ x ≤ 13% was studied in situ using a mechanical load frame. Prior to mechanical ... -
Piezoelectricity and rotostriction through polar and non-polar coupled instabilities in bismuth-based piezoceramics
Acosta, Matias; Schmitt, Ljubomira Ana; Cazorla, Claudio; Studer, Andrew; Zintler, Alexander; Glaum, Julia; Kleebe, Hans-Joachim; Donner, Wolfgang; Hoffman, Mark; Rödel, Jurgen; Hinterstein, Manuel (Peer reviewed; Journal article, 2016)Coupling of order parameters provides a means to tune functionality in advanced materials including multiferroics, superconductors, and ionic conductors. We demonstrate that the response of a frustrated ferroelectric state ...
