Crystal Lattice Distortions associated with a Frustrated Spin System in Trian...
In this proposal, we propose the high-resolution neutron diffraction experiments for AFeO2 (A=Cu and Ag) using HRPD. Although CuFeO2 is well known as one of magneto-electric... -
Structure and Stability of Copper Hydroxy Halides, Products of Anion Exchange...
We have successfully synthesised materials based on naturally occurring minerals and structurally related phases with the formula, Cu2(OH)3X where X is an anion. Phases with the... -
Design of new Ruddlesden Popper phases through sulphate/chromate incorporation
The drive for increasing energy efficiency and reducing greenhouse gas emissions has garnered increasing support for the use of fuel cell technology, which offers the potential... -
Continued studies of the high temperature structural behaviour of Ca2Mn3O8
We recently synthesised a new layered manganes oxide with a frustrated connectivity of Mn4+ ions. Variable temperature studies demonstrated a deviation from linearity at... -

Chemical control of structures and properties of cobalt oxide chalcogenides
The evolution of the crystal structures and magnetic ordering of layered cobalt oxide chalcogenides will be probed as a function of composition. The systems Sr2CoO2Cu2-zSe2 and... -
Investigating the structural effects of bioactivity enhancements in doped hyd...
We wish to gain a deeper understanding of where dopant cations and anions reside in hydroxyapatite (HA). We will substitute Sr, Si, 11B and S into the HA structure and determine... -
Intercalation Mechanisms and Crystal Chemical Lithium Environments in High-Ra...
In this proposal, we seek to explore the crystal chemical environment of intercalated lithium in three related Nb-based oxide materials in order to resolve a mechanistic... -
Variable Temperature Study of thallium and caesium azides
This proposal seeks to investigate the effect of temperature on the structures of thallium and caesium azide. High-resolution neutron powder diffraction data are necessary to... -
Me-ND311BD4: a temperature dependent study of its crystal structure and decom...
We request 4 days on HRPD with the IGAn apparatus to follow the structural changes of Me-ND4 11BD4 as a function of temperature. The high resolution of HRPD will allow us to... -
High-Resolution High-Pressure Study of the Elpasolite Perovskite La2NiMnO6
This proposal sets out to investigate the high pressure behaviour of the double perovskitematerial with the chemical formula La2NiMnO6. The properties of this and related... -
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.... -
Investigating temperature dependent magnetic and crystal structures of misfit...
Thermoelectric materials provide an alternative route for refrigeration and power generation bydirect conversion between thermal and electrical energy. With high chemical... -
Structural Studies of Li(ND3)n11BD4
On exposure to ammonia, Li(11)BD4 forms the ammoniate Li(11)BD4(ND3)n. Our recent experiment (RB820252) has shown that there are four distinct crystalline phases in the... -
In-situ high-resolution study of the Pd-D2 system after passage over the ther...
Our previous HRPD experiment on the Pd-D2 system resolved the long-standing controversy over the occupation of T interstitial sites by D, showing that T sites are occupied owing... -
From giant magneto-elastic coupling to negative thermal expansion
We recently used high-resolution neutron diffraction on HRPD to observe the largest magneto-elastic coupling ever seen in a metallic magnet. The material studied was CoMnSi, a... -
Crystal symmetry change at the magnetic transition in MnB and FeB compounds p...
The "magnetocaloric effect" (MCE) is based on the entropy difference encountered when themagnetic state of a material is changed and it can be used for refrigeration. However,... -
Improper ferroelectricity in hexagonal tungsten bronzes
Ferroelectrics are an important class of materials in modern electronics. Their application range from simple capacitors to ultrasonics transducers and sensors to memory... -
Crystal structure and thermal expansion of acetylene (C2D2)
Acetylene is produced in great abundance in the solar system wherever carbonaceous solids are exposed to energetic radiation. It has been the subject of several studies,... -
The high temperature phases of multiferroic YMnO3
Hexagonal YMnO3 is a well-studied, but poorly understood, multiferroic material, which adopts the 'geometric' mechanism of ferroelectric distortion, rather than the more normal...
