ome results of studying the dielectric and electromechanical properties of ceramic 16BiScO_3–42PbMg_1/3Nb_2/3O_3–42PbTiO_3 relaxor ferroelectric samples in electrical fields (0 10 kV/cm) and explained by the induced ferroelectric phase transition. The field-induced phase (presumably, tetragonal) was shown to be unstable and partially ordered. A nonmonotonical character demonstrated by the dielectric permittivity–time dependences of the studied ceramics unlike the other relaxor ferroelectrics was explained by the coexistence of glassy and ferroelectric phases.
