Stress dependent ferroelectric properties of PZT and 0.9 PZT–0.1 BLT ceramics
Ferroelectrics, 2009•Taylor & Francis
PE hysteresis loops of PZT and 0.9 PZT–0.1 BLT ceramics were determined using a
modified Sawyer-Tower circuit. Ferroelectric properties investigation of the PZT and 0.9 PZT–
0.1 BLT ceramics under stress levels in the range of 0–175 MPa was also carried out. The
result showed that with increasing stress level, a reduction of remanent polarization was
clearly observed. The result was interpreted in terms of non-180° ferroelectric domain
switching processes and the decrease in switchable part of domains induced by stress …

P-E hysteresis loops of PZT and 0.9PZT – 0.1BLT ceramics were determined using a modified Sawyer-Tower circuit. Ferroelectric properties investigation of the PZT and 0.9PZT – 0.1BLT ceramics under stress levels in the range of 0–175 MPa was also carried out. The result showed that with increasing stress level, a reduction of remanent polarization was clearly observed. The result was interpreted in terms of non-180° ferroelectric domain switching processes and the decrease in switchable part of domains induced by stress applied to these materials.
