High pressure behaviour of ammonium carbamate
A number of compounds crystallise in the NH3-H2O-CO2 ternary system, including ammonium carbonates and carbamates, these being closely related to the water-deficient compound... -
Spontaneous surface multilayer formation in oligoamine ¿ surfactant mixtures
This proposal is part of a major EPSRC (EP/GR065705)/Unilever funded programme to develop and control the spontaneous formation of surfactant multilayer structures at... -
Quantum and thermal critical scaling in XY-dipolar antiferromagnet LiErF4
We have established the material LiErF4 as a dipolar antiferromagnet with planar anisotropy, exhibiting both classical and quantum phase transitions. Where, thermal transition... -
Neutron Diffraction Studies of Polycrystalline CeCr1-xTixGe3 (x = 0, 0.5, 1.0)
Observation of both ferromagnetic ordering and Kondo/heavy fermion behavior in a system is not so common. Recently we have discovered the Kondo effect/heavy fermion behavior in... -
In Situ neutron diffraction of liquid gallium at elevated pressure
Gallium has a low melting point and forms a liquid just above room temperature. The melting curve has a negative slope and when pressure is applied room pressure phases will... -
Dynamic Long Range Antiferromagnetic Order in Frustrated Perovskites, Ba2-xSr...
We use chemistry to arrange unusual crystal structures that set up conflicting interactions between magnetic ions in the material. In these compounds i is not possible for a... -
How perfume structure affects surface coadsorption with anionic surfactants
In a recent EPSRC / Unilever / Oxford CASE project we have used NR to explore and develop optimised delivery mechanism for active benefit agents such as perfumes. In particular... -
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... -

Spin and cation order in AMn3B4O12 perovskites
A-site-ordered perovskite oxides with formula AA'3B4O12 have a rich variety of physical and chemical properties. Most have Jahn-Teller active Cu2+ or Mn3+ at the square-planar... -
Inelastic neutron scattering in the Ce3Co4Sn13 heavy Fermion compound
We propose to use the OSIRIS spectrometer to measure the inelastic magnetic scattering on the newly discovered heavy Fermion compound Ce3Co4Sn13. This compound has one of the... -
Magnetic Excitation Spectrum of the Frustrated Antiferromagnet SrYb2O4
In SrYb2O4 the magnetic Yb3+ ions form sub-lattices of double chains running parallel to the crystallographic c-axis with frustrated first and second neighbour antiferromagnetic... -
Phase evolution in the transition from epsilon to gamma glycine
Glycine, the simplest naturally-occurring amino acid, exhibits unusually extensive phase diversity. Three polymorphs are known under ambient conditions. Each shows different... -
Magnetic correlations in the Heavy Fermion Ce3Co4Sn13
Ce3Co4Sn13 is a cubic heavy Fermion system which resides close to a magnetic instability.Under ambient conditions Ce3Co4Sn13 exhibits an extremely large (4 J/mol Ce K2) peak in... -
Neutron Diffraction Analysis of the Crystallography of Early Scientific Instr...
Early scientific instruments are typically made of latten, a quaternary copper alloy (Cu, Zn, Sn, Pb) with many trace elements. The crystallographic structure depends on the... -
Magnon decay below the critical field in the S=1/2 Heisenberg antiferromagnet...
The two dimensional Heisenberg antiferromagnet on a square lattice is one of the most studied model quantum magnets. This is in part due to its intrinsic interest but also to... -
Neutron diffraction experiments on an Etruscan vase
An antique vase from an Etruscan necropolis was made available for neutron-based experiments at ISIS. Preliminary studies on this sample have shown unusual features and opened... -
Soft Modes in the Ferroelectric Semiconductor SbSI
Antimony sulfo-iodide (SbSI) exhibits strongly-coupled photoconductive, semiconducting, and ferroelectric properties. Until the discovery of the lead-oxide ferroelectric relaxor... -
Inelastic neutron scattering study of the field dependent anisotropy of the s...
The bilayer ruthenate Sr3Ru2O7 is the first material found to have a quantum critical end-point and is believed to display ¿nematic electronic order¿. We have previously studied...
