Thermal stability studies of alternating current poled Pb(Mg1/3Nb2/3)O3-PbTiO3 single crystals grown by solid-state crystal growth

open access: yesMaterials Research Letters, 2023
Thermal stabilities of relaxor-PbTiO3 single crystals are of great importance due to their limited operational temperatures in devices. Herein, to elucidate how poling conditions influence thermal stabilities, we investigated direct current (DC) and ...

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 .

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 ...
