Antiferroelectriclike polarization behavior in compositionally varying (1-x) Pb(Mg_1/3Nb_2/3)O₃-(x) PbTiO₃ multilayers

Abstract

Compositionally varying multilayers of (1-x) Pb(Mg_1/3N_2/3)O₃-(x) PbTiO₃ were fabricated using pulsed laser ablation technique. An antiferroelectriclike polarization hysteresis was observed in these relaxor based multilayer systems. The competition among the intrinsic ferroelectric coupling in the relaxor ferroelectrics and the antiferroelectric coupling among the dipoles at the interface gives rise to an antiferroelectriclike polarization behavior. An increment in the coercive field and the applied field corresponding to the polarization flipping at low temperatures, provide further insight on the competition among the long-range ferroelectric interaction and the interfacial interaction in the polarization behavior of these relaxor multilayers.
