Due to the good dielectric, piezoelectric and ferroelectric properties, the pseudo-ternary ferroelectric single crystals Pb(In1/2Nb1/2)O-3-Pb(Mg1/3Nb2/3)O-3-PbTiO3 (PIN-PMN-PT) have been widely concerned and studied. In this study we found that the dynamic hysteresis loop area with electric field E-0 and frequency f(0) of the 0.16 Pb(In1/2Nb1/2)O-3-0.62 Pb(Mg1/3Nb2/3)O-3-0.22PbTiO(3) (0.16PIN-0.62PMN-0.22 PT) single crystals satisfies the relational equation proportional to E(0)(beta)f(0)(alpha). In the proportional to E-beta(0) relationship, both linear stages are found correlated with the low electric field in the first stage E-0 3E(c). The hysteresis loop area with frequency f(0) relationship satisfies the equation . f(0) a with roughly linear trend and the hysteresis loop area decreases with increasing frequency f(0). Such electric field dependent dynamic hysteresis scaling can be observed by polarized light microscopy.
