Lattice dynamical analogies and differences between SrTiO3 and EuTiO3 revealed by phonon-dispersion relations and double-well potentials
Jerry L. Bettis, Myung-Hwan Whangbo, Jürgen Köhler +2
A comparative analysis of the structural phase transitions of EuTiO3 and SrTiO3 (at TS = 282 and 105 K, respectively) is made on the basis of phonon-dispersion and density function…

Coexistence of polar order and local domain dynamics in ferroelectric SrTi18O3
A. Bussmann-Holder, H. Buettner, A. R. Bishop
Perovskite oxide ferroelectrics show classical soft mode behaviour typical for the onset of a homogeneous long-range polar state and a displacive phase transition. Besides these lo…
