Exploring the morphotropic phase boundary in copper(II)-modified Pb[Zr0.54Ti0.46]O3 ferroelectrics

چکیده
Copper(II)-doped Pb[Zr0.54Ti0.46]O3 (PZT) ferroelectrics with a dopant concentration of 0.25 mol % were investigated at high magnetic fields, enabling an enhanced resolution of the structural distortion at the dopant site. The results obtained suggest that Cu2+ substitutes as an acceptor centre for [Zr,Ti]4+ in oxygen octahedra with tetragonal, monoclinic and rhombohedral distortion, confirming the model of mesoscopic mixing at the morphotropic phase boundary.

Néel-like domain walls in ferroelectric Pb(Zr,Ti)O3 single crystals
In contrast to the flexible rotation of magnetization direction in ferromagnets, the spontaneous polarization in ferroelectric materials is highly confined along the symmetry-allowed directions. Accordingly, chirality at ferroelectric domain walls was treated only at the theoretical level and its real appearance is still a mystery. Here we report a Néel-like domain wall imaged by atom-resolved ...

The strain- and polarization-electric field behavior was characterized at room temperature for Pb0.98Ba0.01(Zr1-x Ti x )0.98Nb0.02O3, 0.40 ⩽ x ⩽ 0.60. The investigated compositions were located in the vicinity of the morphotropic phase boundary, giving insight into the influence of crystal structure on the hysteretic ferroelectric behavior. The remanent strain of particular compositions is show...

A first-principles-derived approach is developed to study finite-temperature properties of Pb(Zr1-xTix)O3 (PZT) solid solutions near the morphotropic phase boundary (MPB). Structural and piezoelectric predictions are in excellent agreement with experimental data and direct first-principles results. A low-temperature monoclinic phase is confirmed to exist, and is demonstrated to act as a bridge ...
متن کاملPredicting morphotropic phase boundary locations and transition temperatures in Pb- and Bi-based perovskite solid solutions from crystal chemical data and first-principles calculations
Using data obtained from first-principles calculations, we show that the position of the morphotropic phase boundary MPB and transition temperature at MPB in ferroelectric perovskite solutions can be predicted with quantitative accuracy from the properties of the constituent cations. We find that the mole fraction of PbTiO3 at MPB in Pb B B O3–PbTiO3, BiBO3–PbTiO3, and Bi B B O3–PbTiO3 exhibits...

Dielectric behavior and phase transitions of @001# oriented (12x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 single crystals with x529, 31, 32, and 33 % were investigated by impedance measurements and high resolution x-ray diffraction analysis under various electrical and thermal conditions. Application of a bias field along @001# can shift down the Rhombohedral-Tetragonal structural phase transition, so that the...
