Poling of soft piezoceramic PZT

Effect of phase structure on the dynamic hysteresis scaling behavior in (1−x)BiScO3–xPbTiO3 bulk ceramics

“…From the above, the different behavior in each stage between ln A and ln E 0 strongly suggest different polarization behavior in each stage. In the first stage, the space charge polarization may be main polarization mechanism in this stage [15,16]. The space charge polarization can be attributed to accumulation and release of the mobile charge carriers that arise at the interface between two different interfaces [15][16][17][18].…”

BiFeO3 Thin Films Prepared by Chemical Solution Deposition with Approaches for Improvement of Ferroelectricity

“…Electric field application is to apply a high electric field to reverse its polarization reversal easily. It is typically carried out in bulk materials such as PZT (Kamel et al, 2007). These two approaches are expected to be effective to improve ferroelectric properties of BiFeO 3 thin films (Nakamura et al, 2009).…”

Retention properties with high‐temperature resistance in (Bi,Pr)(Fe,Mn)O3 thin film capacitor

“…Average polarization loss of BPFM film capacitor measured with retention time of 10 4 s and at 450 °C was 3.7 % at most. On the other hand, as shown in the figure, Qsw of PZT film capacitor was drastically decreased with increasing the retention temperature due to their weak heat-resistance [5]. Besides, above 125 °C, it was impossible to evaluate reliable Qsw due to unstable retention behaviour.…”

“…Then, the amount of polarization charge decreased due to the polarization back-switching generated by the internal fields [4,6,13]. Furthermore, PZT thin films showed serious polarization losses at high temperature due to their weak heat-resistance [4][5][6]. Note that this polarization loss was also observed in other ferroelectric materials with high-Tc such as SrBi2Ta2O9 (SBT) [9,14].…”

“…However, it is known that remnant polarization in PZT film capacitors shows serious polarization loss at high temperature [4][5][6]. Many researchers have focused on revealing the mechanism of polarization loss [4,[6][7][8][9][10][11][12].…”
