Abstract
Due to the good dielectric, piezoelectric and ferroelectric properties, the pseudo-ternary ferroelectric single crystals Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (PIN-PMN-PT) have been widely concerned and studied. In this study we found that the dynamic hysteresis loop area <A> with electric field E0 and frequency f0 of the 0.16 Pb(In1/2Nb1/2)O3-0.62 Pb(Mg1/3Nb2/3)O3-0.22PbTiO3 (0.16PIN-0.62PMN-0.22 PT) single crystals satisfies the relational equation <A> ∝ E0βf0α. In the <A> ∝ E0β relationship, both linear stages are found correlated with the low electric field in the first stage E0<Ec and the high electric field in the third stage E0 > 3Ec. The hysteresis loop area <A> with frequency f0 relationship satisfies the equation <A> ∝ f0α with roughly linear trend and the hysteresis loop area <A> decreases with increasing frequency f0. Such electric field dependent dynamic hysteresis scaling can be observed by polarized light microscopy.
