摘要：

The electrostriction in Pb (Zn 1 3Nb 2 3)O3 crystals has been investigated using a strain gauge method. In the ferroelectric phase below 140 C, the strain vs the electric field shows a hysteresis, which is ascribed to the effect of ferroelectric domains. A quadratic relation holds between the strain x and the electric polarization P as x = QP2 above about 170 C in the paraelectric phase. Values of the electrostrictive Q coefficients are determined from the measurements near 190 C, as Q11 = 1.6·10-2m4/C2, Q12 = -0.86·10-2m4/C2, and Q44 = 0.85·10-2m4/C2. © 1979.
