TL;DR: High-resolution x-ray diffraction, Raman spectroscopy and total scattering XRD coupled to atomic pair distribution function (PDF) analysis studies of the atomic-scale structure of archetypal BaZrxTi(1-x)O3 reveal the presence of Ti-rich polar clusters which are precursors of a long-range ferroelectric order observed below TC.

TL;DR: In this article, it was shown that the tetragonal (T) and rhombohedral (R) structures of (1−x)BiFeO3-xPbTiO3 are stable for xT⩾0.31 and xR⩽0.27, respectively, giving the narrowest width of 0.03.

TL;DR: In this paper, an anomalous peak in the composition dependence of the dielectric permittivity of non-ferroelectric ceramics was reported, which was linked with a change of crystal structure from one orthorhombic phase in the $Pbma$ space group for $0.10lxl 0.10$ to another orthor-ombic phases in the Pbnm$ space groups for $x\ensuremath{\geqslant}0.20$ through an intermediate long period modulated orthorHombic

TL;DR: In this article, a controlled tuning of the temperature coefficient of resistance (TCR) can be done by modifying the structural parameters and chemical environment of the compounds, achieving the result of negative TCR in an ordered, non-Kondo crystalline compound.

TL;DR: In this article, the authors show that the increased displacement of yttrium atoms along the polar c axis of the hexagonal unit cell may result in enhanced local ferroelectric distortions with decreasing particle size.
