摘要：
A tetragonal (IT) <----> monoclinic (M) phase transition characterized by a wide thermal hysteresis is observed in Pb(Zn1/3Nb2/3)O-3-PbTiO3 (PZN-PT) single crystals close to the morphotropic composition PZN-9%PT, The domain structure of crystals. determined by X-ray diffraction and optical observations. is dependent on the poling, crystallographic direction. A monoclinic quasi-single domain structure is obtained by poling along the pseudocubic [10 (1) over bar] direction whereas an unexpected monoclinic multidomain state with macroscopic 2 mm symmetry can be obtained for [001] poled crystals, Finally it is shown that the largest piezoelectric response corresponds to the monoclinic multidomain State of, [001] poled crystals.
