| Abstract: | The dynamic hysteresis scaling behaviors of Nb‐doped Pb(Zr0.52Ti0.48)O3 ceramics have been investigated as a function of electric field amplitude (E0) and frequency (f) at different temperatures (T). The loop area <A> of saturated loops is found to follow various power laws as <A> ∝ E00.3065 at fixed f and <A> ∝ f 0.0120 at fixed E0. Furthermore, the linear scaling relation <A> = k3 fαE0β + b3 is estimated under various temperatures. The exponents α (=0.01) and β (=0.10) are T‐independent, whereas the slopes k3 and y‐intercepts b3 are T‐dependent because the increasing temperature in the same phase range only decreases the threshold field of the reversal rather than change the dynamic reversal process. |
