Abstract
The evolution of the dielectric permittivity and loss factor under an external applied electric field has been studied in PbMg1/3Nb2/3O3 Cer amics 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 p hase to a macroscopically polar phase. The poling and depoling tempera tures 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.
