Strontium barium niobate (SrxBa1-xNb2O6, shortly SBN) is a solid solution system with tetragonal tungsten bronze crystal structure. It exhibits a ferroelectric phase with only one polar axis and a transition temperature depending on the Sr/Ba ratio. This t ...
Relaxor-ferroelectric single crystals PZN-xPT [(1-x)Pb(Zn1/3Nb2/3)O3-xPbTiO3] and PMN-xPT [(1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3] continue to attract much interest due to their anomalously large piezoelectric properties (d33 > 2000 pm/V; k33 > 90%) when poled ("do ...
The lead magnesium niobate [Pb(Mg1/3Nb2/3)O-3 or PMN], and its solid solutions with lead titanate (PbTiO3 or PT), are of great interest because of their high electromechanical properties. At large PMN content, these materials exhibit relaxor characteristic ...
The converse piezoelectric response of Pb(ZrxTi1−x)O3 ceramics is investigated as a function of material composition. The effects of the crystallographic phase and different dopants on piezoelectric nonlinearity are separately examined. For a linear depend ...
The continuous downscaling of microelectronic circuits combined with increasing interest in ferroelectric thin films for non-volatile random access memories (FeRAM) is drawing great attention to small ferroelectric thin film structures. There are various c ...
The orientation dependence of the longitudinal piezoelectric coefficient, d(33)(*), is investigated as a function of temperature in BaTiO3 and PbTiO3 crystals using the Landau-Ginsburg-Devonshire theory. We show that a presence of the ferroelectric-ferroel ...
Using electrodeposition from a bath of molten fluorides, single crystals of tetragonal beta-tantalum have been obtained for the first time at normal pressure. The unit-cell parameters are a = 10.211 (3), c = 5.3064 (10) Angstrom, space group P (4) over bar ...
The pyroelectric coefficients of 0.72Pb(Mg1/3Nb2/3)O-3-0.28PbTiO(3) (PMN-28PT), 0.67Pb(Mg1/3Nb2/3)O-3-0.33PbTiO(3) (PMN-33PT), and 0.92 Pb(Zn1/3Nb2/3)O-3-0.08PbTiO(3) (PZN-8PT) single crystals, oriented and poled along three different crystallographic dire ...
Direct measurements of longitudinal (d(33)) and transverse (d(31)) piezoelectric coefficients have been made on cuboid samples of 001-poled 0.955Pb[Zn1/3Nb2/3]O-3-0.045PbTiO(3) (PZN-4.5PT) and 0.68Pb[Mg1/3Nb2/3]O-3-0.32PbTiO(3) (PMN-32PT) single cryst ...
This article reviews recent advances in the studies of the piezoelectric properties of perovskite materials. Perovskite compositions are the best known and the largest family of ferroelectric and piezoelectric materials.: The dependence of the longitudinal ...
