Dielectric and electromechanical properties of ceramic solid solutions PbMg_1/3Nb_2/3O₃—PbZr_0.53Ti_0.47O₃

Nonlinear Dielectric Response of Relaxor PMN-PZT Ceramics under DC Electric Field

“…Its temperature position and degree of phase transition diffusion depend on a composition of solid solution [17]. For all compositions at a temperature of 12 • C the dc electric field with strength 15 kV/cm, applied across a sample, resulted in noticeable permittivity decrease measured at a frequency of 800 Hz (Fig.…”

Dielectric and Elastic Properties of Relaxor PbMg1/3Nb2/3O3

“…The expression (5) with the experimental values of Q 33 ≈ 1.5 · 10 −2 m 4 /C 2 at T = 300 K [12] and P S = 14 · 10 −2 C/m 2 [13] leads to a ≈ 3 · 10 −4 . Using this value and the experimental data from the temperature dependences of the internal friction and the shear modulus (Fig.…”

Low‐frequency 1/f noise in relaxor ferroelectric PMN–PZT

“…the dispersion becomes weaker as x in (1 -х)PMN-хPZT is increased. This shows the attenuation of relaxation properties in the relaxor system studied [8,9].…”
