Figure 1: Imaginary part of the dielectric responses of BZT as a function of frequency.
From: Fano resonance and dipolar relaxation in lead-free relaxors

(a) The dielectric response from Zr cells, χZr,Zr. (b) The dielectric response from Ti cells, χTi,Ti. (c) The dielectric response from the cross-correlation between Ti and Zr cells, χTi,Zr. (d) The total dielectric response. The solid lines in these panels represent the fitting of the MD data using analytical expressions given in equations (6) and (7), and Q(ν). The actual MD data are also shown (in blue colour) in order to confirm the adequacy of the fittings.
