Structural Chirality and Natural Optical Activity across the $α$-to-$β$ Phase Transition in SiO$_2$ and AlPO$_4$ from first-principles Open
Natural optical activity (NOA), the ability of a material to rotate the plane of polarized light, has traditionally been associated with structural chirality. However, this relationship has often been oversimplified, leading to conceptual …

Ferroelastic domain hierarchy in the intermediate state of PbZr0.98Ti0.02O3 single crystal Open
PbZrO3-based antiferroelectric crystals are of great interest in both fundamental and applied research, not only because of the antiferroelectric feature at room temperature but also because of the existence of a peculiar intermediate stat…

A re-examination of antiferroelectric PbZrO$_3$ and PbHfO$_3$: an 80-atom $Pnam$ structure Open
First principles density functional theory (DFT) simulations of antiferroelectric (AFE) PbZrO$_3$ and PbHfO$_3$ reveal a dynamical instability in the phonon spectra of their purported low temperature $Pbam$ ground states. This instability …

Confusion over the description of the quartz structure yet again Open
In a recent paper [Huang, Gog, Kim, Kasman, Said, Casa, Wieczorek, Hönnicke & Assoufid (2018). J. Appl. Cryst. 51 , 140–147], a description of the structure of quartz was given that is incorrect. There is a long history of such errors in p…

Local-scale structures across the morphotropic phase boundary in PbZr<sub>1−<i>x</i> </sub>Ti<i> <sub>x</sub> </i>O<sub>3</sub> Open
Lead zirconate titanate (PZT) is one of the most widely studied piezoelectric materials, mainly because of its `mysterious' relationship between the so-called morphotropic phase boundary (MPB) and its strong piezoelectric coupling factor. …

Crystallographic and optical study of LiNb<sub>1 − <i>x</i></sub>Ta<i><sub>x</sub></i>O<sub>3</sub> Open
Powders of lithium niobate-tantalate across the full compositional range have been made and crystals grown using a lithium vanadate flux growth technique. The Li-content of a lithium tantalate crystal has been determined using the zero-bir…

Crystallographic and optical study of PbHfO<sub>3</sub> crystals Open
The symmetry of the intermediate high-temperature phase of PbHfO 3 has been determined unambiguously to be orthorhombic using a combination of high-resolution X-ray diffraction and birefringence imaging microscopy measurements of crystal p…

Reconsidering the origins of Forsbergh birefringence patterns Open
In 1949, Forsbergh, Jr. reported spontaneous spatial ordering in the birefringence patterns seen in flux-grown $\mathrm{BaTi}{\mathrm{O}}_{3}$ crystals under the transmission polarized light microscope [Phys. Rev. 76, 1187 (1949)]. Stunnin…
