Abstract:
The high-pressure structure and dynamics of PbZr0.40Ti0.60O3 were investigated by means of neutron diffraction, X-ray diffraction, and resonance Raman spectroscopy. The complex (P4mm, Cm, Cc, F1, F1) phase transition sequence is characterized by these techniques. On the basis of the results of structure refinements, the high-pressure behavior of the spontaneous polarization, the (Zr,Ti)O6 rotation angles, and the polarization rotation angle are obtained. Moreover, resonance Raman spectra combined with previous Raman data in the literature provide evidence that the pressure-induced transition to the monoclinic Cm space group and the above transition sequence terminating in a paraelectric state are general features of Pb(Zr(1-x)Ti(x))O3 (0.48 < or = x < or = 1).
