摘要：

The evolution of the dielectric permittivity and loss factor under an external applied electric field has been studied in PbMg1/3Nb2/3O3 Ceramics between 80 and 420 K. For a threshold field of 4 kV.cm-1, it is possible to induce a ferroelectric transition from the average cubic phase to a macroscopically polar phase. The poling and depoling temperatures depend on the various combinations of thermal treatments and on the applied field strength. The transition between the nanopolar state and the macropolar state is discussed.
