Neutron analysis of the structure of SrAl2O4 from 300 to 1273 K.
SrAl2O4 is a stuffed tridymite that has attracted a good deal of interest, since doping with Eu2+ leads to a material with elastic-luminescent response. The structure and phase... -

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... -
The Magnetic Structure of LaCoxMn1-xO3 (x = 0.75)
It is the aim of the current proposal to examine in detail the magnetic structure of LaCo0.75Mn0.25O3 at low temperature, which should provide insight into the nature of the... -
The structures of PZT in its ¿rhombohedral¿ phases and their dependence on th...
In the piezoelectric ceramic material PbZrxTi1-xO3 (PZT) there is controversy about the structure of PZT at the Zr-rich end. This region has always been considered to be of... -
The ferroelectric phase transition in Dion-Jacobson layered perovskites - con...
Ferroelectricity in the Dion-Jacobson (DJ) family of layered perovskites arises from a 'trilinear coupling', whereby two non-polar lattice modes interact in such a way to... -
Electronically-driven structural transition in Ti-doped Ca3Ru2O7
The purpose of the experiment is to determine the effect of titanium doping on the structural and magnetic transitions of Ca3Ru2O7. The pure material undergoes a Néel transition... -
Low temperature crystallography on two new compounds with mobile cations
Structure solution of materials with very high ionic mobilities, and/or small populations of moderately mobile ions is hampered because the scattering from these ions is... -
Investigating the role of oxygen in the mechanism for the transformation from...
Materials for Solid Oxide Fuel Cells (SOFCs) are being developed continuously. Cuprous delafossites (CuBO2 where B=Cu, Cr) are being developed for cathode side applications in... -
Completing the Magnetic Ordering-Crystal Structure Phase Diagram of Supercond...
The key objective is to measure three samples of composition Fe(1.05)Te, Fe(1.12)Te, and Fe(1.14)Te as a function of temperature (base to 80 K) through their magnetic ordering... -
Potassium Vanadates: Potential Electrode Materials for Lithium Batteries
A high-resolution powder neutron diffraction study of the potassium bronzes KV5O13 and K2V8O21 is proposed. The structure of KV5O13 is unknown, while K2V8O21 is believed to... -
Strain/order parameter coupling and anomalous elastic properties of Sr(Ti,Zr)...
HRPD data will be collected in situ at low and high temperatures from perovskites belonging to the Sr(ZrxTi1-x)O3 solid solution which have recently been characterised for their... -

What is the Room Temperature Structure of NaTaO3?
The current proposal seeks to establish the origin of t non-perovskite-like peak splitting observed in HRPD data for NaTaO3. It is our hypothesis that this is a result of the... -
Strain effect on the magnetic ground state of the ferroelectric Ca3CoMnO6 system
The search for new ferroelectric materials, where the ferroelectricity results from magnetic frustration, has been a topic of great interest to the condensed matter physics... -
Structures and compositions of Li-conducting framework materials with low sym...
Re-chargeable Li ion batteries play a key role in modern consumer electronics and may have an important part to play as energy storage devices in a low carbon economy of the... -
Thermal expansion of Mg: pre-melting effects in hcp metals and the Earth's in...
Ab initio computer simulations have suggested that pre-melting phenomena occur in the elastic properties of hcp-iron at the conditions of the Earths inner core just before... -
Unravelling the mechanisms of negative thermal in γ-Mg(11BD4)2
We request 2 days on HRPD to perform a detailed study of the low temperature behaviour of γ-Mg(11BD4)2 in order to measure the change lattice parameter as a function of... -
Neutron diffraction to monitor the state of a non-stoichiometric solid employ...
An unmixed reaction is a dynamic process in which e.g. a metal oxide (which acts as an oxygen-carrier material) is used to e.g. provide oxygen for a reaction during which the...
