(Color online) Fitting of Peq to the PMN saturation polarization data from 200 to 300 K (Ref. 6) and Pdyn to temporal E-poling data of PMN-0.08PT crystal (Ref. 17).
(Color online) Comparison of Eq. (3) predicted thermal evolution of ν with the measured E c of PMN crystal (taken from Ref. 6); the inset shows the linear relation between ν and E c .
(Color online) (a) Variation of calculated normalized V (open box) with temperature based on the measured ΔP data (circle) of PMN crystal in Ref. 6; The curve is obtained from the percolation theory according to V = 0.08/(1-203.1/T) while the solid box represents the experimental correlation length R c observed by NEDS in Ref. 7. (b) Fitting of χst with respect to normalized ΔP (circle), and plot of Eq. (4) predicted χdyn at various 1/τf values with respect to U. (c) Variation of χ from Eq. (4) with U. The diamonds in (b) and (c) denote the shift of Um,f and Um,f , while the solid and hollow arrows indicate the direction of increasing f and T, respectively.
(Color online) (a) Plots of (circle), the predicted (thick curve) as well as measured (box) ν/2, and the fitting of V-F relation (line); the experimental ν/2 data (i.e., the four labeled frequencies) is taken from Ref. 19. (b) f-dependence of Vst/V f; the linear fitting denotes Merz’s switching law, i.e., 1/E c ∼ Vst/V f ∼ ln (1/f).
