摘要：

yPiezoelectric constant and temperature-dependent dielectric constant measurements have been performed on <110>-oriented (1 - x)Pb(Mg1/3Nb2/3)O-3-xPbTiO(3) crystals with different compositions under different poling fields. The width of the morphotropic phase boundary region (0.30 < x < 0.35) is determined on the basis of two abnormal regions of the dielectric and piezoelectric properties. An irreversible rhombohedral-monoclinic M-A-monoclinic M-C-tetragonal phase transition sequence was observed directly from the dielectric constant versus temperature results for <001>-poled rhombohedral crystals with compositions near the rhombohedral-monoclinic phase boundary. The structure of the morphotropic phase is shown to be monoclinic with space group P-m.
