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 ... -
Giant Functional Properties in Porous Electroceramics through Additive Manufacturing of Capillary Suspensions
Menne, David; Lemos Da Silva, Lucas; Rotan, Magnus; Glaum, Julia; Hinterstein, Manuel; Willenbacher, Norbert (Peer reviewed; Journal article, 2022)Dedicated hierarchical structuring of functional ceramics can be used to shift the limits of functionality. This work presents the manufacturing of highly open porous, hierarchically structured barium titanate ceramics ... -
Nonlinear mechanical behaviour of Ba0.5Sr0.5Co0.8Fe0.2O3 − δ and in situ stress dependent synchrotron X-ray diffraction study
Geiger, Philipp T.; Clemens, Oliver; Khansur, Neamul H.; Hinterstein, Manuel; Sahini, Mtabazi Geofrey; Grande, Tor; Tung, Patrick; Daniels, John E.; Webber, Kyle G. (Journal article; Peer reviewed, 2017)Perovskite type Ba0.5Sr0.5Co0.8Fe0.2O3 − δ ceramics display nonlinear stress-strain behaviour upon uniaxial compression at room temperature. Step functional loading experiments show that the nonlinear strain response of ... -
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 ... -
Revealing the role of local stress on the depolarization of BNT-BT-based relaxors
Glaum, Julia; Heo, Yooun; Acosta, Matias; Sharma, Pankaj; Seidel, Jan; Hinterstein, Manuel (Journal article; Peer reviewed, 2019)Canonical relaxors exhibit an electric-field-induced phase transition between a macroscopically nonpolar and polar phase that can be tuned from being stable at low temperature to being reversible at high temperature. The ...
