چکیده
Domain switching behavior of 0.955Pb~Zn1/3Nb2/3!O3 – 0.045PbTiO3 ferroelectric single crystal has been investigated using the ultrasonic technique in addition to the polarization hysteresis measurements. The ultrasonic technique makes it possible to extend the coercive field measurement to frequencies as low as 10 Hz, revealing the existence of a saturated coercive field Esc , which representing the intrinsic switching barrier. © 2002 American Institute of Physics. @DOI: 10.1063/1.1448385#

Domain configurations in domain engineered 0.955Pb„Zn1Õ3Nb2Õ3...O3 – 0.045PbTiO3 single crystals
We report an optical microscopy study on the domain structures of 0.955Pb~Zn1/3Nb2/3!O3–0.045PbTiO3 rhombohedral phase single crystals poled along @001# of the cubic coordinates. Both charged and uncharged domain walls are observed in domain engineered samples and they could join together to form ‘‘L’’ and ‘‘T’’ shaped domain walls, which are very unique. The observed domains are between 10 and...
متن کاملSwitching Mechanism in Single Crystal 0.955Pb(Zn1/3Nb2/3)O3-0.045PbTiO3
Direct experimental evidence is given to show that the traditional viewpoint of polarization reversal must be modified to include the path of consecutive non-180◦ domain switching. Using ultrasonic waves, we have successfully monitored multi-domain formation during the polarization switching cycle in a bulk single crystal 0.955Pb(Zn1/3Nb2/3)O3-0.045PbTiO3. A model is proposed for the polarizati...
متن کاملComplete set of properties of 0.92Pb(Zn1/3Nb2/3)O3–0.08PbTiO3 single crystal with engineered domains
This paper reports the complete set of elastic, piezoelectric and dielectric constants of 0.92Pb(Zn1/3Nb2/3)O3–0.08PbTiO3 domain engineered single crystal. We found that the piezoelectric strain constant d33 and dielectric permittivity e33 T of this crystal are larger than that of 0.955Pb(Zn1/3Nb2/3)O3–0.045PbTiO3 reported earlier. Fluctuations of the values of piezoelectric and dielectric cons...

The temperature dependence of piezoelectric, pyroelectric, and dielectric properties have been measured for 001 and 111 oriented 0.92Pb Zn1/3Nb2/3 O3–0.08PbTiO3 PZN-8%PT and 0.955Pb Zn1/3Nb2/3 O3–0.045PbTiO3 PZN-4.5%PT single crystals poled by two different poling methods, i.e., room temperature RT poling and poling through field cooling FC . Compared with the RT poling case, some interesting f...

A detailed investigation has been conducted on the dielectric anomalies induced by different electrical and thermal conditions in @111# oriented 0.955Pb(Zn1/3Nb2/3)O320.045PbTiO3 ~PZN-4.5%PT! single crystals. Application of a dc electrical field to the crystal results in field induced dielectric anomalies to occur at specific temperatures, which can be explained by the structural phase transiti...
