Determining fundamental properties from diffraction: Electric field induced strain and piezoelectric coefficient
Hinterstein, Manuel; Lee, Kaiyang; Esslinger, Sophia; Glaum, Julia; Studer, Andrew; Hoffman, Mark John; Hoffmann, Michael (Peer reviewed; Journal article, 2019)Neutron powder diffraction was used in operando to determine the macroscopic strain and piezoelectric coefficient as a function of applied electric field in a technically relevant actuator material. We were able to ... -
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 ...
