Dynamic ferroelectric hysteresis scaling of BaTiO3 single crystals
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 E0 were clearly established. Above the coercive field, the scaling took a form of 〈A〉 f-0.195 E0 0....

| Summary: | 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 E0 were clearly established. Above the coercive field, the scaling took a form of 〈A〉 f-0.195 E0 0.950. On the other hand, the scaling in the form of 〈A〉 f1.667 E0 -2.804 E0 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 E0 exponents depended on E0 and f, respectively, which was in contrast to the prior theoretical prediction and experimental investigations. © 2009 American Institute of Physics. |
