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…
