We have investigated both the polarization rotations and the field induced phase transitions in [100], [110], and [111]-oriented PZN-4.5% PT single crystals on the basis of the single domain polarization rotation model. The dependence of the polarization, the electrostrictive response, and the lattice parameters in ferroelectric crystals on the field has been numerically obtained. The numerical results, in agreement with the experimental data, have shown that the polarization rotation is strongly dependent on the initial polarization state and polarization history in the single crystals, and the rhombohedral-monoclinic-tetragonal phase transitions occur for E//[100].
