Stress-dependent scaling behavior of subcoercive field dynamic ferroelectric hysteresis in Pb(Zn1∕3Nb2∕3)O3-modified Pb(Zr1∕2Ti1∕2)O3 ceramic

Abstract

Scaling behavior of subcoercive field dynamic ferroelectric hysteresis under influence of stress was investigated in Pb(Zn1∕3Nb2∕3)O3-modified Pb(Zr1∕2Ti1∕2)O3 (PZT) bulk ceramic. The scaling relation of hysteresis area ⟨A⟩ against frequency f, field amplitude E0, and stress σ for the minor loops takes a form of ⟨A−Aσ=0⟩∝f−0.42E03.65σ0.24, which is very similar to that of soft and hard PZT ceramics. However, slightly faster responses to f and E0 indicate the ease of polarization orientation in this simpler domain structure ceramic as compared to commercial PZT ceramics.
