Résumé

PZT solid solutions were studied as a function of pressure and temperature by neutron and x-ray diffraction, Raman spectroscopy and dielectric measurements. Pressure was found to favour low-symmetry structures (Cm, Cc, F1, F ) characterized by a rotation and a reduction of the spontaneous polarisation and by the tilting of (Zr,Ti)O6 octahedra leading to unit cell doubling (except Cm space group). Additionally, our results show that for Ti-rich PZT, high pressures stabilize the ferroelectric monoclinic phases responsible for the high piezoelectric properties of the MPB composition.
