Figure 4: Temperature dependence of the Debye frequency associated with the RTi–Ti relaxational mode of Ti ions.

From: Fano resonance and dipolar relaxation in lead-free relaxors

Figure 4

(a) The dependence in linear scales is shown in a, while in b such frequency is shown in logarithmic scale with τTi–Ti being in unit of second, and as a function of the ratio of 1,000 and the temperature (expressed in Kelvin). The solid line in both panels corresponds to the fitting by an Arrhenius law, 1/τTi–Ti = ν0 exp(−U/kBT).
