Abstract: Longitudinal electrostrictive strains in an as-sintered and two annealed (0.4)Pb(In1/2Nb1/2)O3 : (0.6)Pb(Mg 1/3Nb2/3)O3 relaxor ceramics were measured by laser-interferometry. The field-related electrostriction coefficients (M 33) of the ceramics were then determined. The electrostrictive coefficients progressively decreased with annealing and the strain responses became nonlinear. The ferroelectric hysteresis loops of the as-sintered and annealed ceramics showed progressive decrease in coercive fields and maximum polarizations with increasing annealing time. Transmission electron microscopy studies revealed enlargement of 1 : 1 B-site ordered domains with annealing. The changes in the high-field responses of the annealed ceramics are interpreted as arising from a higher degree of long-range order caused by annealing. A field-induced mechanism is proposed to explain the correlation between the B-site cation long-range order and the electrostrictive behaviour in this relaxor.
