Phenomenological Theory of High Permittivity in Fine-Grained Barium Titanate
TL;DR: In this paper, the anomalously high permittivity in fine-grained ceramic barium titanate is explained by the absence of 90° twinning within the grains, giving rise to internal stresses as the ceramic cools below the Curie temperature.

Relaxation polarization of PbMg 1/3Nb2/3O3(PMN)-A ferroelectric with a diffused phase transition
V. V. Kirillov,V. A. Isupov +1 more
TL;DR: In this article, a model has been proposed, in accordance with which the features of the dielectric properties PMN are explained by the relaxation of the polar regions surrounded with a non polar phase, with the number of relaxing regions dependent on temperature.

Variation of Permittivity with Electric Field in Perovskite‐Like Ferroelectrics
TL;DR: In this article, a model for polycrystalline ferroelectrics is considered, in which each crystallite is assumed to behave according to a free energy function of the type formulated by A. F. Devonshire [Advances in Phys. 3, 85 (1954)] for BaTiO3.

Grain size effects on the ferroelectric-paraelectric transition, the dielectric constant, and the lattice parameters in lanthana-substituted lead titanate
K. Keizer,A. J. Burggraaf +1 more
TL;DR: In this article, the effect of the grain size on unit-cell dimensions and dielectric properties has been studied in ceramic lanthana-substituted lead titanate of the general composition Pb1-αxLaxTiO3+x (15-α) with α = 120 and x = 007 (PLT7) and X = 018 (PLTs18) The grain size ranges from 06 to 11 µm and the effects are most pronounced on the smaller sizes.
