摘要：

The scaling behavior of the dynamic hysteresis of ferroelectric BaTiO3 single crystals was investigated. Two sets of the scaling relation of hysteresis area < A > against frequency f and field amplitude E-0 were clearly established. Above the coercive field, the scaling took a form of < A >proportional to f(-0.195)E(0)(0.950). On the other hand, the scaling in the form of < A >proportional to f(0)(1.667E)-2.804E(0)(4.157) was obtained under subcoercive field condition. While these scaling relations were generally comparable to previously reported ones, it was found that the f and E-0 exponents depended on E-0 and f, respectively, which was in contrast to the prior theoretical prediction and experimental investigations.
