摘要：
The temperature dependence of dielectric properties for a PMN0.32PT single crystal under different dc electric fields (E) has been investigated. The dielectric responses and phase transition behaviors of this material are provided. With an increasing electric field, both phase transition temperatures of rhombohedral to tetragonal phase and tetragonal to cubic phase increased. When E = 1.5-4.0 kV/cm, a new phase is induced by an electric field. The phase transition and the induced new phase were discussed. (C) 2003 Elsevier Science B.V. All rights reserved.
