The influence of rare-earth additives, such as La, Nd, Sm, and Gd, and poling conditions on the electromechanical properties of (Pb[sub 1[minus]3x/2]Ln[sub x])(Ti[sub 0.98]Mn[sub 0.02])O[sub 3] 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 electro-mechanical anisotropy (k[sub t]lk[sub p]) 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.
