Role of Zinc and Niobium in the Giant Piezoelectric Response of PbZn1/3Nb2/3O3
Ali Al-Zein, Hichem Dammak, Philippe Papet +5
Relaxor ferroelectric perovskites are highly polarizable and can exhibit giant coupling between elastic strain and an applied electric field. Here, we report an in situ extended X-…
Influence of thermal history on the structure and properties of silicate glasses
Claire Levelut, Rozenn Le Parc, Annelise Faivre +1
We studied a set of float glass samples prepared with different fictive temperature by previous annealing around the glass transition temperature. We compared the results to previo…
Universal behavior of internal friction in glasses below T : anharmonicity vs relaxation
Jacques Pelous, Claire Levelut
Comparison of the internal friction at hypersonic frequencies between a few K and the glass transition temperature Tg for various glasses brings out general features. At low temper…
Influence of fictive temperature and composition of silica glass on anomalous elastic behaviour
R Le Parc, C Levelut, J Pelous +2
In order to point out the influence of thermal history (fictive temperature) and OH content on the elastic properties of silica glass, we have performed high resolution in situ Bri…
Dynamic sound attenuation at hypersonic frequencies in silica glass
Claire Levelut, Rozenn Le Parc, Jacques Pelous
In order to clarify the origin of the dominant processes responsible for the acoustic attenuation of phonons, which is a much debatted topic, we present Bril louin scattering exper…
In situ measurements of density fluctuations and compressibility in silica glass as a function of temperature and thermal history
Claire Levelut, Annelise Faivre, Rozenn Le Parc +3
In this paper, small-angle X-ray scattering measurements are used to determine the different compressibility contributions, as well as the isothermal compressibility, in thermal eq…
