Resum
Dielectric and piezoelectric responses are investigated in relaxor-like lanthanum-modified lead zirconate titanate (PLZT) ceramics, for a La/Zr/Ti ratio of x/60/40 (x = 8 and 10 at.%), obtained by the conventional ceramic method. No significant differences were observed from the room temperature ferroelectric properties, for both PLZT compositions. On the other hand, from evaluation of the nonlinear dielectric response in terms of the Rayleigh’s model, a typical ‘soft’ behaviour is achieve...
