Abstract
New (1−x)Ba(Y1/2Nb1/2)O3-xPbTiO3 ceramics have been synthesized by conventional mixed-oxide process. Two morphotropic phase boundaries (MPBs) corresponding to the rhombohedral-orthorhombic and orthorhombic-tetragonal phases are observed with increasing PT. The appearance of E(2TO1), E(2TO2), silent, Rl and E(4LO) modes indicates the presence of an orthorhombic symmetry. Remarkable variation with two MPBs appears in the whole frequency region, where the rhombohedral modes change into the tetragonal ones in the system.
