Stability of the tetragonal phase of BaZrO3 under high pressure
Constance Toulouse, Danila Amoroso, Robert Oliva +8
In this paper, we revisit the high-pressure behavior of BaZrO3 by a combination of first-principle calculations, Raman spectroscopy, and x-ray diffraction under high pressure. We c…
Lattice dynamics and Raman spectrum of BaZrO3 single crystals
Constance Toulouse, Danila Amoroso, Cong Xin +7
BaZrO3 is a perovskite that remains in the simple cubic phase at all temperatures, hence with no first-order Raman-active phonon mode allowed by symmetry. Yet, it exhibits an inten…
Persistent type-II multiferroicity in nanostructured MnWO4 ceramics
Pascaline Patureau, Remi Dessapt, Philippe Deniard +5
We show that the type-II multiferroic properties of bulk MnWO4 are kept in nanostructured ceramics of 50 nm grain size prepared via spark plasma sintering (SPS). This means that fe…
Drastic changes of electronic structure and crystal chemistry upon oxidation of SnII2TiO4E2 into SnIV2TiO6: an ab initio study
Samir F. Matar, Mario Maglione, Michel Nakhl +2
From DFT based calculations establishing energy-volume equations of state and electron localization mapping, the electronic structure and crystal chemistry changes from Sn2TiO4 to…
Intrinsic ionic screening of the ferroelectric polarization of KTP
Mario Maglione, Anand Theerthan, Vincent Rodriguez +4
Mobile charges and lattice polarization interact in ferroelectric materials because of the Coulomb interaction between the mobile free charges and the fixed lattice dipoles. We hav…
Magnetic field tuning of polaron losses in Fe doped BaTiO3 single crystals
R. Anand Theerthan, Alla Artemenko, Mario Maglione
Artificial tuning of dielectric parameters can result from interface conductivity in polycrystalline materials. In ferroelectric single crystals, it was already shown that ferroele…
