چکیده
We report the presence of a field-induced intermediate ferroelectric phase in pre-poled [111] oriented 0.955Pb(Zn1 / 3Nb2 / 3)O3– 0.045PbTiO3 (PZN–4.5%PT) single crystals, based on the dielectric, differential scanning calorimetry and pyroelectric measurements. It was found that this phase exists in a very narrow interval of 4.3 -C between the ferroelectric rhombohedral and tetragonal phases. This may be explained as an electric-field-induced orthorhombic phase based on previous investigations on the PZN–8%PT single crystals. An electricfield-induced phase diagram of <111> oriented PZN–PT has been redrawn based on this study. D 2005 Elsevier B.V. All rights reserved. PACS: 77.22.-d; 77.84.Dy; 64.70.-p

Electric field-induced phase transitions were investigated in (111), (110), and (100) thin platelets of relaxor ferroelectric Pb(Mg1∕3Nb2∕3)O3 single crystals with electric fields applied along the ⟨111⟩, ⟨110⟩, and ⟨100⟩ directions, respectively.

Pb(In(12)Nb(12))O(3)-Pb(Mg(13)Nb(23))O(3)-PbTiO(3) (PIN-PMN-PT) single crystals have been developed recently, which can increase the operating temperature by at least 20 degrees C compared to PMN-PT crystals.

متن کاملElectric field dependence of nonlinearity parameters and third order elastic constants of 0.70Pb(Mg(13)Nb(23))O(3)-0.30PbTiO(3) single crystal.
Through second harmonic measurements, the ultrasonic nonlinearity parameters of [001](c) and [111](c) polarized 0.70Pb(Mg(13)Nb(23))O(3)-0.30PbTiO(3)(PMN-0.3PT) single crystals have been measured as a function of bias electric field. It was found that the nonlinearity parameter increases almost linearly with field at low field but shows a drastic increase near the coercive field. The [111](c) p...
