Abstract

The evolution of the dynamic hysteresis with electrical field amplitude (E0) and frequency (f) in the relaxor-based ferroelectric 0.71Pb(Mg1/3Nb2/3)O3–0.29PbTiO3 (PMN-29PT) single crystal has been investigated systematically. Our results showed that the electric field dependent scaling relationship in PMN-29PT single crystal can be divided to three regions, and the hysteresis area <A> follows the power law <A>∝fαE0β in the low and high E0 regions, but the power law is not obeyed in the intermediate region due to the complex collective contributions of 180° and non-180° domains. The frequency dependent scaling relationship can be separated into two regions, and presents a unique behavior when the field level E0 is equal or lower than the coercive field Ec. The hysteresis area decreases continually with the increase of frequency when E0 < Ec, while <A> first increases then decreases for high E0 situation (E0 ≥2Ec). Related electrical field and frequency dependent polarization reversal mechanisms are proposed based on the experimental observations.
