Abstract
Neutron diffraction data obtained on single crystals of with and , which lie on the pseudorhombohedral side of the morphotropic phase boundary, suggest a coexistence of rhombohedral () and monoclinic () domains and that monoclinic order is enhanced by Ti substitution. A monoclinic phase with a doubled unit cell () is ruled out as the ground state.
