Abstract
The influence of rare‐earth additives, such as La, Nd, Sm, and Gd, and poling conditions on the electromechanical properties of (Pb1−3x/2Lnx)(Ti0.98Mn0.02)O3 compositions, x= 0.04–0.12, were investigated. The type and amount of additive were found to affect the lattice anisotropy, dielectric constant, and electromechanical properties. A large electromechanical anisotropy (kt/kp) could be obtained in 10 mol% Sm‐modified and 8 mol% Gd‐modified lead titanate ceramics, and seemed to correlate to a low Poisson's ratio.
