Thermal dependence of the mechanical properties of NiTiSn using first-principles calculations and high-pressure X-ray diffraction
P. Hermet, J. Haines, D. Granier +2
In this work we aim to study the effect of temperature on the mechanical properties of a solid. For this, we have introduced a new first-principles based methodology to obtain the…
Revealing the complex nature of bonding in binary high-pressure compound FeO
E. Koemets, I. Leonov, M. Bykov +21
Extreme pressures and temperatures are known to drastically affect the chemistry of iron oxides resulting in numerous compounds forming homologous series FeOFeO…
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-…
Piezo-ferroelectrics: Pressure-induced phase transitions in Pb(Zr1-xTix)O3 (PZT)
Jérôme Rouquette, Julien Haines, Véronique Bornand +1
Piezoelectric PZT solid solutions were studied as a function of pressure and temperature. Moderate pressure is found to induce phase transitions to monoclinic phases (Cm,Cc) for Ti…
Use of resonance Raman spectroscopy to study the phase diagram of PbZr0.52Ti0.48O3
Jerome Rouquette, Julien Haines, Véronique Bornand +3
Evidence is presented for the first time that the sharp and continuous spectral changes observed in PbZr0.52Ti0.48O3 (PZT) between 350 and 10 K with the 647.1 nm wavelength are due…
