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 fα E0β + 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.
