The dynamic hysteresis scaling behaviors of Nb‐doped Pb(Zr 0.52 Ti 0.48 )O 3 ceramics have been investigated as a function of electric field amplitude ( E 0 ) and frequency ( f ) at different temperatures ( T ). The loop area of saturated loops is found to follow various power laws as ∝ E 0 0.3065 at fixed f and ∝ f 0.0120 at fixed E 0 . Furthermore, the linear scaling relation = k 3 f α E 0 β + b 3 is estimated under various temperatures. The exponents α (=0.01) and β (=0.10) are T ‐independent, whereas the slopes k 3 and y ‐intercepts b 3 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.
