Oxide pyrochlores — A review
Journal ArticleDOI
Heteroanionic Materials by Design: Progress Toward Targeted Properties.
TL;DR: The field of anion engineering in oxide-based compounds aims to tune physical properties by incorporating additional anions of different size, electronegativity, and charge as discussed by the authors, which can span a more complex atomic structure design palette and interaction space than the homoanionic oxide-only analogs.

An Unexpected Crystal-Chemical Principle for the Pyrochlore Structure
TL;DR: This paper showed that pyrochlore does not form at chemical compositions predicted by the traditional formula for this crystal structure, A2B2O6O', where A denotes large (8-coordinated, e.g. Bi3+) and B small (6coordinated), e. g. Zn2+, Nb5+) cation sites.

Lone pairs in insulating pyrochlores: Ice rules and high-k behavior
TL;DR: In this paper, the electronic structure of cubic Bi 2 Ti 2 O 7 was visualized and compared with the electronic structures of the Aurivillius phase ferroelectric SrBi 2 Ta 2 O 9 (SBT), which displays a ferro electric distortion below 608 K associated with the tendency of lone pair active Bi 3+ to move off-center.

Ferroelectric and antiferroelectric materials with pyrochlore structure
TL;DR: In this article, the existence of three phase transitions at 106°C, 184°C and 282°C for the pyrochlore structure of Cd2NB2O6S.
