In this paper we present a Raman-scattering study of the phase transitions in the (formula presented) 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 (formula presented) We also studied the monoclinic-tetragonal phase boundary and our spectroscopic results agree very well with those reported by using x-ray diffraction. © 2002 The American Physical Society.
