Significant Increment of the Dielectric Permittivity and Domain Properties in the (1-x)PbTiO3-x(Na0.5Bi0.5)TiO3 Crystals [PDF]

open access: yesArchives of Metallurgy and Materials, 2020
Crystals of PbTiO3 and 0.9PbTiO3-0.1(Na0.5Bi0.5)TiO3 were obtained by the flux growth method whereas crystals of (Na0.5Bi0.5)TiO3 were growth by the Czochralski method. Raman spectroscopy and polarized light microscopy were performed at room temperature.

Perovskite lead-based oxide anodes for rechargeable batteries

open access: yesElectrochemistry Communications, 2021
Lead-based perovskites (PbTiO3 and PbZrO3) are introduced as novel anode materials for non-aqueous M-ion rechargeable batteries (M = Li, Na, K). These compounds were scalably prepared by conventional solid-state (dry) and combustion (wet) routes.

Perovskite solid solutions with multiferroic morphotropic phase boundaries and property enhancement [PDF]

open access: yesJournal of Advanced Dielectrics, 2016
Recently, large phase-change magnetoelectric response has been anticipated by a first-principles investigation of phases in the BiFeO3–BiCoO3 perovskite binary system, associated with the existence of a discontinuous morphotropic phase boundary (MPB ...

Influence of KF substitution on the ferroelectric phase transition of lead titanate single crystals studied by Brillouin light scattering [PDF]

open access: yesJournal of Advanced Dielectrics, 2015
The elastic properties of KF-substituted perovskite lead titanate (PbTiO3) were investigated by dielectric measurements and Brillouin light scattering. The ferroelectric phase transition occurred at substantially lower temperature due to KF substitution,

Absence of critical thickness for polar skyrmions with breaking the Kittel’s law

open access: yesNature Communications, 2023
The period of polar domain (d) in ferroics was commonly believed to scale with corresponding film thicknesses (h), following the classical Kittel’s law of d ∝ $$\sqrt{h}$$ h .

Structural and electronic properties of monodomain ultrathin PbTiO3/SrTiO3/PbTiO3/SrRuO3 heterostructures: A first-principles approach [PDF]

open access: yesJournal of Applied Physics, 2020
First-principles calculations within the local density approximation were carried out to explain the ground state and electronic properties of a vacuum/PbTiO3/SrTiO3/PbTiO3/SrRuO3 multilayer in a monodomain phase. Open-circuit boundary conditions were assumed, considering the electric displacement field, D, as the fundamental electrical variable.

Disordered ferroelectricity in the PbTiO3/SrTiO3 superlattice thin film

open access: yesAPL Materials, 2017
The PbTiO3/SrTiO3 superlattice thin films with a low volume fraction of PbTiO3 have not attracted much interest because they are thought to exhibit only a paraelectric state.
