Neutron diffraction data obtained on single crystals of PbZr(1-x)Ti(x)O3 with x=0.325 and x=0.460, which lie on the pseudorhombohedral side of the morphotropic phase boundary, suggest a coexistence of rhombohedral (R3m/R3c) and monoclinic (Cm) domains and that monoclinic order is enhanced by Ti substitution. A monoclinic phase with a doubled unit cell (Cc) is ruled out as the ground state.
对位于准同型相界伪菱面体侧的 PbZr(1-x)Ti(x)O3 单晶体（x=0.325 和 x=0.460）进行的中子衍射实验表明，存在菱面体（R3m/R3c）和单斜（Cm）畴的共存，并且 Ti 取代增强了单斜有序。排除了具有两倍单元胞（Cc）的单斜相作为基态。
