This review puts in doubt the classical description of the Verwey (metal–insulator) transition
in magnetite on the basis of the wide set of experiments carried out over the last 60 years …

Applications of computer-based group-theoretical methods to perovskite crystallography are
reviewed. Such methods furnish a systematic account of the effects on the high-symmetry …

Although both A-and B-site cations have the same simple cubic topology in the perovskite
structure they typically adopt different patterns of chemical order. As a general rule B-site …

The crystal structure of highly stoichiometric magnetite (Fe 3 O 4) below the Verwey
transition has been refined from high-resolution neutron and synchrotron x-ray powder …

Strong coupling between the chemical composition and crystal lattice dimensions resulting
in the contraction or expansion of a material upon change of its chemical composition is …

Unlike ordering of the octahedral B-site cations, ordering of the larger A-site cations in
stoichiometric perovskites is rare. Herein the A-and B-site ordering characteristics of several …

Materials demonstrating high ion diffusivity are currently attracting a great deal of attention
owing to their huge technological potential. We have found that the oxygen diffusivity in …

Hydrogen-associated electron-doping Mottronics for d-band correlated oxides (eg, VO2)
opens up a new paradigm to regulate the electronic functionality via directly manipulating …

Long range ordering of two transition metal charge (oxidation) states occurs in many oxides.
Direct structural evidence from powder neutron diffraction studies on several half-doped …

YBaFe2O5 has been synthesized by heating a nanoscale citrate precursor in a carefully
controlled reducing environment. Successful synthesis of a single-phase sample can only …
