Abstract

0.7Bi1-xNdx (Fe0.9Cr0.1) O3-0.1BaTiO3-0.2PbTiO3 (x = 0, 0.03, 0.05, 0.07) solid solutions were prepared by the traditional ceramic process. X-ray diffraction results revealed that all samples showed pure rhombohedral perovskite structure. The addition of Nd substitutions could decrease the coercive field and electrical insulation resistivity. The P-E loops of specimens with x = 0.03 and 0.05 attained saturation. Piezoelectric constant d33 of the solid solutions increased firstly and then decreased, but the Magnetization of the solid solutions decreased slightly with increasing of the Nd content.
