Dynamic Hysteresis Scaling in BaTiO3 Bulk Ceramics

Abstract

The scaling behavior of the dynamic hysteresis of ferroelectric BaTiO3 bulk ceramics was investigated. Two sets of the scaling relation of hysteresis area <A> against frequency f and field amplitude E0 were clearly established. Approximately, above the coercive field, the scaling took a form of <A>  f -0.23E00.87. On the other hand, the scaling in the form of <A>  f -0.36E03.64 was obtained under a sub-coercive field condition. While these scaling relations were generally comparable to previously reported ones, it was found that the f- and E0 exponents clearly depended on E0 and f, respectively.
