Gonçalves da SilvaWe have investigated the behavior of the PbZr0.94Ti0.06O3 Raman spectra as a function of hydrostatic pressure. New structural phases were identified based on previous works performed in a PZT system with different Ti concentrations at room and high pressures. We showed that PbZr0.94Ti0.06O3 exhibits a rich phase sequence up to 3.7GPa: rhombohedral(LT)→0.3GPaorthorhombic(I)→2.9GPaorthorhombic(I′). This sequence is different from that exhibited by PbZr0.90Ti0.10O3, suggesting an interesting concentration–pressure phase diagram for a rich Zr PZT system.A. InsulatorsD. Phase transitionsE.
