Studies of local order and clustering in (1-x)BaTiO3-xBiYbO3 Perovskites
We propose total scattering experiments on samples of (1-x)BaTiO3-xBiYbO3 perovskites with x = 0, 0.04, 0.08 and 0.15 to resolve issues over the local structure and degree of... -
Magnetostructural study of Percolation Behaviour in Double Perovskites Ba2Fe1...
We propose to use two days of beamtime on POLARIS to determine the structure and magnetic ordering that occurs in a series of cation-ordered perovskites. These cubic compounds... -
Phase Separation and Jahn Teller Distortion in Molybdate Perovskites
Two days of beamtime on HRPD will be used to examine a family of double perovskites Sr2YbMO6 that are isostructural at room temperature. When M = Mo5+ the monoclinic perovskite... -
The role of Disorder in Phase Transitions in some manganese Perovskites
The aim of this work is to understand the origin of the difference in the behaviour between the two doped manganites Sr0.65Pr0.35MnO3 and Sr0.70Ce0.30MnO3. The hypothesis we... -
A Self-consistent Description of the Thermoelastic Properties of Dielectric P...
20 years ago, Anderson proposed that the thermoelastic properties of the dominant (mantle) phase within the Earth, MgSiO3 perovskite, could be described as a simple Debye solid.... -
The geometric blueprint of perovskites
Perovskite minerals form an essential component of the Earth’s mantle, and synthetic crystals are ubiquitous in electronics, photonics, and energy technology. The extraordinary... -
Electronic structure of pristine and Ni-substituted LaFeO₃ from near edge x-r...
We present a joint theoretical and experimental study of the oxygen K-edge spectra for LaFeO₃ and homovalent Ni-substituted LaFeO₃ (LaFe₀.₇₅Ni₀.₂₅O₃), using first-principles...
