Giant photostriction in lead-free ferroelectric stemming from photo-excited thermalized carriers
Gaëlle Vitali-Derrien, Oana Condurache, Antoine Ducournau +14
Ferroelectrics are polar materials whose polarization can be switched by applying electric fields; they offer unique opportunities to develop performant photostrictive materials, i…
Strain-induced polarization rotation in freestanding ferroelectric oxide membranes
Alban Degezelle, Razvan Burcea, Pascale Gemeiner +7
Freestanding ferroelectric membranes have emerged as a versatile tool for strain engineering, enabling the exploration of ferroelectric properties beyond traditional epitaxy. The r…
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…
Optical and electronic properties in ferroelectric barium titanate-based compounds
Ingrid C. Infante, Halyna Volkova, Pascale Gemeiner +9
The bandgap energy values for the ferroelectric BaTiO3-based solid solutions with isovalent substitution Ba1-x SrxTiO3, BaZrxTi1-xO3 and BaSnxTi1-xO3 were determined using diffuse…
Magnetodielectric coupling and phonon properties of compressively strained EuTiO3 thin films deposited on LSAT
S. Kamba, V. Goian, M. Orlita +13
Compressively strained epitaxial (001) EuTiO3 thin films of tetragonal symmetry have been deposited on (001) (LaAlO3)_0.29-(SrAl_{1/2}Ta_{1/2}O3)_0.71 (LSAT) substrates by reactive…
Surface phase transitions in BiFeO3 below room temperature
R. Jarrier, X. Marti, J. Herrero-Albillos +15
We combine a wide variety of experimental techniques to analyze two heretofore mysterious phase transitions in multiferroic bismuth ferrite at low temperature. Raman spectroscopy,…
Multiferroic phase transition near room temperature in BiFeO3 films
I. C. Infante, J. Juraszek, S. Fusil +13
In multiferroic BiFeO3 thin films grown on highly mismatched LaAlO3 substrates, we reveal the coexistence of two differently distorted polymorphs that leads to striking features in…
A new temperature scale T* in lead-based relaxor systems
B. Dkhil, P. Gemeiner, A. Al-Barakaty +4
Via a combination of various experimental and theoretical techniques, a peculiar, identical temperature scale T* is found to exist in all complex lead-based relaxor ferroelectrics.…
