Dynamic Hysteresis and Scaling Behavior of Energy Density in Pb0.99 Nb0.02[( Zr0.60 Sn0.40)0.95 Ti0.05] O3 Antiferroelectric Bulk Ceramics.

The evolution of dynamic hysteresis of lead zirconate titanate stannate antiferroelectric bulk ceramics at various frequencies ( f) and field amplitudes ( E0) has been investigated systematically. A series of asymmetrical minor loops were observed when the working fields were slightly lower than the forward switching field EAF. As E0 increased above EAF, symmetrical double loops appeared and their energy densities w against f and E0 were found to be fit the scaling behavior as w [ABSTRACT FROM AUTHOR]
