Effect of cation dynamics on polar instabilities of perovskite derived structures — •Rinis Ferizaj1, Florian Büscher1, Peter Lemmens1, Hiroshi Kageyama2, and Tong Zhu21IPKM, TU Braunschweig — 2Energy Chemistry, Univ. Kyoto, Japan

Perovskite derived structures have a huge variability in structural, electronic and magnetic properties. This makes them leading candidates for todays search for novel energy materials. Using Raman scattering we probe phonon dynamics in such material and focus to the cation dynamics to better understand transitions into different polar/nonpolar low temperature phases.

We acknowledge support by DFG GrK 1952/2, Metrology for Complex Nanosystems-NanoMet, and DFG EXC-2123 QuantumFrontiers - 390837967.
