Magnetic field enhanced structural instability in EuTiO_{3}
Z. Guguchia, H. Keller, J. Kohler +1
EuTiO_{3} undergoes a structural phase transition from cubic to tetragonal at T_S = 282 K which is not accompanied by any long range magnetic order. However, it is related to the o…
Hybrid paramagnon phonon modes at elevated temperatures in EuTiO3
A. Bussmann-Holder, Z. Guguchia, J. Köhler +3
EuTiO3 (ETO) has recently experienced an enormous revival of interest because of its possible multiferroic properties which are currently in the focus of research. Unfortunately ET…
The polarizability model for ferroelectricity in perovskite oxides
Annette Bussmann-Holder
This article reviews the polarizability model and its applications to ferroelectric perovskite oxides. The motivation for the introduction of the model is discussed and nonlinear o…
Structural instability of EuTiO3 from X-ray powder diffraction
J. Köhler, R. Dinnebier, A. Bussmann-Holder
We have recently predicted and subsequently verified experimentally by specific heat measurements that EuTiO3 undergoes a structural phase transition at elevated temperature TS = 2…
