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