Dynamic hysteresis and scaling behavior for Pb(Zr,Ti)O3 ceramics

The dynamic hysteresis of Nb-doped Pb(ZrxTi1-x)O-3 (PZT, 0.40 <= x <= 0.60) ceramics with different phase structures was investigated as functions of frequency f and electric field amplitude E-0. When E-0 grows over similar to 1.5 times of coercive field E-c, all the loops become well saturated and their scaling relations of hysteresis area < A > against f and E-0 can be expressed with an identical form as < A > proportional to f(0.01)E(0)(0.10) for either tetragonal phase or morphotropic phase, which is in good agreement with our previous result of rhombohedral PZT [Chen et al., J. Appl. Phys. 114, 244101 (2013)]. The results indicate that ferroelectrics with fairly distinct domain structures could have similar dynamic hysteresis and scaling behavior at high-E-0 region.
