Consistent transition model for Bi0.5Na0.5TiO3 from temperature-dependent structural and electrical properties
Thomas Fourgassie, Omar Ibder, Cosme Milesi-Brault +5
BNT based solid solutions are promising parent materials for lead free dielectric capacitors, thanks to their high recoverable energy densities and breakdown strengths. However, th…
Phonon studies of the phase transition sequence in antiferroelectric single crystal of Pb(Hf0.83Sn0.17)O3
Anirudh K. R., Cosme Milesi-Brault, Christelle Kadlec +5
The sequence of phase transitions in PbHf0.83Sn0.17O3 has been studied by THz, far infrared and Raman spectroscopies, revealing the complementary behaviour of both, polar and non-p…
Band gap tuning by structural phase transition in Sm-substituted BiFeO3 powders
Christina Hill, Michele Melchiorre, Cosme Milesi-Brault +6
The substitution of bismuth by samarium in BiFeO3 is known to induce a structural phase transition from the polar phase to a non-polar phase, with a possible antiferroelectric inte…
Coexisting polarization mechanisms in ferroelectric uniaxial tetragonal tungsten bronze Ca_0.3Ba_0.7Nb_2O_6
E. Buixaderas, Š. Svirskas, C. Kadlec +6
Using a broad band dielectric spectroscopy approach (1 to 10^14 Hz) we prove that the tungsten bronze Ca0.3Ba0.7Nb2O6 (CBN-30) displays a ferroelectric phase transition of mixed di…
Anharmonicity of the antiferrodistortive soft mode in barium zirconate BaZrO
Petter Rosander, Erik Fransson, Cosme Milesi-Brault +6
Barium zirconate (BaZrO) is one of the very few perovskites that is claimed to retain an average cubic structure down to \SI{0}{\K}, while being energetically very close to an…
Birefringence induced by antiferroelectric switching in transparent polycrystalline film
Pranab Parimal Biswas, Cosme Milesi-Brault, Alfredo Blázquez Martínez +7
The most characteristic functional property of antiferroelectric materials is the possibility to induce a phase transition from a non-polar to a polar phase by an electric field. H…
Critical field anisotropy in the antiferroelectric switching of PbZrO3 films
Cosme Milesi-Brault, Nicolas Godard, Stéphanie Girod +6
Antiferroelectrics have been recently sparking interest due to their potential use in energy storage and electrocaloric cooling. Their main distinctive feature is antiferroelectric…
Archetypal soft-mode driven antipolar transition in francisite Cu3Bi(SeO3)2O2Cl
Cosme Milesi-Brault, Constance Toulouse, Evan Constable +8
Model materials are precious test cases for elementary theories and provide building blocks for the understanding of more complex cases. Here, we describe the lattice dynamics of t…
