Overview of the Structural, Electronic and Optical Properties of the Cubic and Tetragonal Phases of PbTiO3 by Applying Hubbard Potential Correction. [PDF]

open access: yesMaterials (Basel), 2023
We have performed a systematic study resulting in detailed information on the structural, electronic and optical properties of the cubic (Pm3¯m) and tetragonal (P4mm) phases of PbTiO3 applying the GGA/PBE approximation with and without the Hubbard U ...

Parameter-free prediction of phase transition in PbTiO3 through combination of quantum mechanics and statistical mechanics [PDF]

open access: yesScripta Materialia, 2022
Thermodynamics of ferroelectric materials and their ferroelectric to paraelectric (FE-PE) transitions including those in PbTiO3 is commonly described by the phenomenological Landau theory and more recently by effective Hamiltonian and various potentials,

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.

Comparative Hybrid Hartree-Fock-DFT Calculations of WO2-Terminated Cubic WO3 as Well as SrTiO3, BaTiO3, PbTiO3 and CaTiO3 (001) Surfaces

open access: yes, 2021
We performed, to the best of our knowledge, the world’s first first-principles calculations for the WO2-terminated cubic WO3 (001) surface and analyzed the systematic trends in the WO3, SrTiO3, BaTiO3, PbTiO3 and CaTiO3 (001) surface ab initio ...

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,

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 ...

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 .

Electron spin resonance of Gd3+ in ceramic PbTio3 [PDF]

open access: yes, 1976
The electron spin resonance spectra of Gd3+ in ceramic PbTiO3 and, as a comparison, in powdered Bi3Mg2(NO3)12·24H2O are reported. The interpretation, in terms of crystal field parameters, of the spectrum of the double nitrate is in good agreement with ...

Monodomain to polydomain transition in ferroelectric PbTiO3 thin films with La0.67Sr0.3MnO3 electrodes [PDF]

open access: yes, 2006
Finite size effects in ferroelectric thin films have been probed in a series of epitaxial perovskite c-axis oriented PbTiO3 films grown on thin La0.67Sr0.33MnO3 epitaxial electrodes. The film thickness ranges from 480 down to 28 A (7 unit cells).
