Ultrahigh permittivity in core-shell ferroelectric ceramics: Theoretical approach and practical conclusions
M. Anoufa, J. M. Kiat, C. Bogicevic
Ferroelectric anomalies in most classical ferroelectric materials such as BaTiO3 (BT) and related compounds tend to become diffuse and eventually vanish when the grain size decreas…
Simulating the radiofrequency dielectric response of relaxor ferroelectrics: Combination of Coarse-Grained Hamiltonians and Kinetic Monte Carlo
Gregory Geneste, L. Bellaiche, Jean-Michel Kiat
The radiofrequency dielectric response of the lead-free Ba(ZrTi)O relaxor ferroelectric is simulated using a coarse-grained Hamiltonian. This concept, taken fro…
Second harmonic generation and X-ray diffraction studies of pretransitional region in relaxor K(1-x) LixTaO3
Hiroko Yokota, Yoshiaki Uesu, Charlotte Malibert +1
Optical second-harmonic-generation(SHG) observations and precise X-ray diffraction experiments have been performed on quantum paraelectrics KTaO3 (KTO) and relaxor K(1-x)LixTaO3 wi…
A combined theoretical and experimental study of the low temperature properties of BaZrO3
A. R. Akbarzadeh, I. Kornev, C. Malibert +2
Low temperature properties of BaZrO3 are revealed by combining experimental techniques (X-ray diffraction, neutron scattering and dielectric measurements) with theoretical first-pr…
Polar Order in Quantum Paraelectric SrTiO3-16 and SrTiO3-18 at Low Temperature
Yoshiaki Uesu, Ryuhei Nakai, Jean-Michel Kiat +3
Optical second-harmonic generation (SHG) in SrTi16O3 (STO16) and SrTi18O3 (STO18) was investigated using the SHG microscope. While no-biased STO16 exhibits weak and almost temperat…
Monoclinic structure of unpoled morphotropic high piezoelectric (PbMg1/3Nb2/3O3)0.65-(PbTiO3)0.35 and (PbZn1/3Nb2/3O3)0.91-(PbTiO3)0.09 compounds
J-M. Kiat, Y. Uesu, B. Dkhil +3
Evidences of a monoclinic phase in unpoled (PbMg1/3Nb2/3O3)1-x-(PbTiO3)x with x=0.35 (PMN-PT 35%) and unpoled (PbZn1/3Nb2/3O3)1-x-(PbTiO3)x with x=0.09 (PZN-PT 9%) are presented fr…
