Relaxor Pb(Mg1/3Nb2/3)O3(PMN) and its solid solutions with ferroelectric PbTiO3 (PT) are of considerable interest from both the applications and the scientific point of view. In the past, many attempts were made to prepare and study the properties of these ...
Pyrochlore free Pb(Mg1/3Nb2/3)O-3 (PMN) thin films were prepared from alkoxide-based solution precursors. The influence of different seeding layers and chemical solution on the microstructures is shown. Dielectric, electrostrictive, and piezoelectric prope ...
The contribution of domain walls to the dielectric permittivity of ferroelectrics is customarily explained by the model of locally pinned walls. Here we analyze the complementary case and calculate wall contribution to permittivity of a sample in which 180 ...
Dielectric properties of perovskites are studied both to gain insight into fundamental aspects of the freezing of polar disorder, and to investigate their technological potential. The dynamics of freezing of polar disorder is investigated in single crystal ...
Pb(Zr0.70Ti0.30)O-3 rhombohedral thin films of (100), (110)/(111) and (111) textures were prepared on Si wafers with Ti/Pt electrodes. Microstructures and textures were characterized by XRD, SEM, TEM, and AFM. Ferroelectric, dielectric and fatigue properti ...
The evolution of switching polarization (P-r(s)) suppression, in Pb(Zr,Ti)O-3 films, induced by two different electric treatments is addressed in terms of the nonlinear dielectric response. The ac electric field dependence of dielectric permittivity was co ...
Pb(Mg1/3Nb2/3)O-3 thin films were prepared from modified alkoxide solution precursors and their dielectric and electromechanical characteristics were investigated. Preparation of the films is very sensitive to processing parameters. The influence of differ ...
The non-linear dielectric properties of single crystals of PbMg1/3Nb2/3O3 relaxer ferroelectric were investigated experimentally by using measurements of the dielectric permittivity of this material as a function of the DC bias and the AC driving fields. T ...
It is shown that the effects of large de bias and ac driving fields on the dielectric permittivity of single crystals of PbMg1/3Nb2/3O3 (PMN) relaxer ferroelectric exhibit very different behavior, including anisotropy and sign of the effect, which is trace ...
