Abstract

Transverse and longitudinal elastic strain have been measured for electric fields applied along the 〈100〉 direction in single crystals of lead magnesium niobate [Pb(Mg_1/3Nb_2/3)0₃], using a bonded strain gauge technique. A quadratic electrostrictive relation holds between induced elastic strain and electric polarization for temperatures near the low-frequency dielectric maximum. The electrostriction coefficients are almost temperature independent with values Q₁₁=2.50×10 ^-2 m⁴/C² and Q₁₂=-0.96×10 ^-2 m⁴/C². To check the direct measurements, the hydrostatic Q coefficient was determined independently by measuring the pressure dependence of the dielectric permittivity. The value Q_h =0.60×10^-2 m⁴/C² obtained is in good agreement with that calculated from the direct measurements.
