Abstract

The polarization versus field (P-E) characteristics of modified Pb(Mg_1/3Nb_2/3)O₃-PbTiO₃ (PMN-PT) and Pb(Sc_1/2Nb_1/2)O₃-PbTiO₃ (PSN-PT) ceramics has been investigated for compositions close to the morphotropic phase boundary. Investigations were performed for various types of lower valent substituents on the B-site cation positions. It has been found possible to introduce "hard" P-E characteristics in "soft" PMN-PT and PSN-PT ferroelectric ceramics. In PMN-PT, only Mn was found to be effective in introducing such characteristics, however, in PSN-PT various lower valent substituents on higher valent sites were found to be effective. The results indicate that using a defect-engineering approach that it may be possible to develop materials with combinatory characteristics of hard and soft ferroelectrics.
