Pressure-Tuning Interactions in Spin-Crossover Metal-Organic Frameworks
The magnetism of spin-crossover (SCO) materials containing Fe(II) can be switched by changing conditions. The low-spin state existing at low temperature or high pressure can be... -
Colossal Magnetoresistance in PrBa2Cu3O7-d
Large negative bulk magnetoresistance has recently been observed in ruthenocuprate materials RuSr2R2-xCexCu2O10-d (up to -47 % at 5 K in a 9 T field). This material exhibits -MR... -
Competetive adsorption in hydrophobin / protein mixtures at the air-solution ...
Hydrophobins are secreted fungal proteins in the form of small lipopetide biosurfactants. They are strongly surface active and self assemble at interfaces and in solution. This... -
Self-assembly in biosurfactants and biosurfactant / surfactant mixtures
This proposal is part of a new project which is a collaboration between Oxford, Newcastle, Ulster, and Unilever on the development of sustainable laundry detergents, using... -
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... -
Structural and magnetic characterisation of polar magnetic perovskite-based m...
A new generation of low-power high-density information storage would be enabled by the development of ?multiferroic? materials which function at or above room temperature. Such... -
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... -

This experiment aims to map out the structural phase diagram of the new multiferroic compound hexagonal-YbFeO3 as a function of temperature, both above and below room... -
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... -
Towards an accurate structural phase diagram for the novel BiScO3-PbTiO3 ferr...
The aim of this experiment is to determine accurately the crystal structures of phases in the (1-x)BiScO3-xPbTiO3 (BST-PT) perovskite phase diagram, particularly in the vicinity... -
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... -
Anion disorder in Ti pyrochlores as a precursor in the transition to fluorite
The aim of this work is to understand the nature of anion disordering in pyrochlore oxides and to establish what, if any, correlations exist between the anion position, disorder... -
Complex evolution of solution microstructure in LAS / nonionic surfactant mix...
This proposal is part of a broad programme of collaborative research between RAL / Oxford and Unilever, using predominantly scattering techniques to investigate the nature of... -
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... -
Quantum-Critical Dynamics of a 3-dimensional Antiferromagnet
We have recently discovered a pressure-induced quantum phase transition (QPT) at 4.3 kbar in the gapped quantum magnet piperazinium hexachlorodicuprate (PHCC) by means of... -
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... -
Crystal and magnetic structures of new ruthenate perovskites
Ruthenate perovskites have a diverse range of electronic properties originating from electron-electron correlations within broad 4d bands. We have recently investigated the high... -
