The complex dielectric permittivity of the morphotropic phase boundary ͓001͔-oriented PMNx % PT single crystal with x = 33%, grown by the modified Bridgman technique, has been investigated as a function of both temperature and dc poling field. Structural phase transformation sequence is discussed in the light of polarization rotation process. A remarkable shift in the rhombohedral-tetragonal phase transition temperature is observed with changing of the poling field. It is found that high
