Raman scattering study of the PbZr1-xTixO3 system:: Rhombohedral-monoclinic-tetragonal phase transitions -: art. no. 132107

In this paper we present a Raman-scattering study of the phase transitions in the PbZr1-xTixO3 systems around the morphotropic phase boundary over a wide temperature range. The boundary between rhombohedral and monoclinic phases was found to be a quasivertical line between x=0.46 and x=0.47. We also studied the monoclinic-tetragonal phase boundary and our spectroscopic results agree very well with those reported by using x-ray diffraction.
