    • High piezoelectricity by multiphase coexisting point: Barium titanate derivatives 

      Gao, Jinghui; Ke, Xiaoqin; Acosta, Matias; Glaum, Julia; Ren, Xiaobing (Journal article; Peer reviewed, 2018)
      BaTiO3-based lead-free piezoelectric materials have long been known as “a mediocre class of piezoelectric materials.” However, they have seen significant renewed interest in recent years ever since the discovery of high ...

    • 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 ...
