Crystal-structure dependent domain-switching behavior in BaTiO3 ceramic
Crystal-structure dependent dynamic scaling behavior was investigated for BaTiO 3 ceramic. The scaling relation of the form 〈A〉 ∝ f M E n 0 , (where 〈A〉 is the area under the hysteresis loop, while f and E 0 represent the frequency and amplitude of the applied electric field signal) was used to d...

| Summary: | Crystal-structure dependent dynamic scaling behavior was investigated for BaTiO 3 ceramic. The scaling relation of the form 〈A〉 ∝ f M E n 0 , (where 〈A〉 is the area under the hysteresis loop, while f and E 0 represent the frequency and amplitude of the applied electric field signal) was used to determine the values of parameters m and n at various temperatures in the range of -90 °C to 170 °C. The variations in the values of parameters m and n with temperature are explained in terms of the effect of the crystallographic nature of BaTiO 3 . The values of parameters m and n obtained for the paraelectric regime suggest that the hysteresis in the P-E (polarization-electric field) loops is related to the dielectric loss rather than any domain-related phenomenon. © 2014 IOP Publishing Ltd. |
