Low-energy spin dynamics of a quantum analogue of ice
Quantum spin liquids are exotic states of magnetic matter in which conventional magnetic ordering is suppressed. Magnetic analogues of ice are good candidates to observe this... -
Magnetic Structure of the double charge ordered multiferroic perovskites HgMn...
Understanding the magnetic structure of the perovskite manganites has been a significant field of research over the past 20 year due of their numerous technologically relevant... -
Spin waves in as-grown PLCCO-- How doping without annealing affects the spin ...
We propose to study the spin wave excitations of nonsuperconducting single crystal Pr0.88LaCe0.12CuO4 (PLCCO). Previous experiments on superconducting PLCCO have shown that spin... -
Thermal expansion of kyanite, andalusite and sillimanite
Al2SiO5 forms three naturally-occurring polymorphs, kyanite, andalusite and sillimanite. These minerals are produced by varying degrees of metamorphism of sedimentary rocks, the... -
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... -
Effect of Q on the INS spectrum of coordinated small molecules in frameworks:...
We request 3 days on MARI to investigate the effect of Q on the previously determined partial phonon density of states of a zeolite framework with a low concentration of... -
Superconducting state arising out of a Topological Crystalline Insulator
A new class of materials called Topological Crystalline Insulator(TCI) has been recently proposedtheoretically and subsequently, SnTe has been discovered to exhibit all the... -
Low Temperature Magnetic Behaviour of Sm2Zr2O7
Pyrochlore oxides of the type A2B2O7 (where A = trivalent rare earth, B = tetravalent transition metal element) can form geometrically frustrated magnets displaying a range of... -
Thermodynamics of Non-Uniform Compression in H-Bonded Molecular Solids
Equations of state (EoSs) show how the thermodynamic variables of temperature, pressure and volume are inter-related. The ideal gas law, PV = nRT, is an example of an EoS which... -
Are magnetic excitations in the Yb based pyrochlores really gapless?
A recent neutron study of a powder sample attests a splayed ferromagnetic structure for Yb2Ti2O7. However in the same work the authors report gapless magnetic excitations even... -
Magnetic ordering in the layered honeycomb alpha-RuCl3
This proposal is part of our research programme to explore novel phases stabilized by the combined effect of spin-orbit interaction and electron correlations. Here we aim to... -

Confined water in a geo-polymer system
The main objective of this proposal is to investigate the dynamics of ultra-confined water in the slits pores of geological cavities (mineral tobermorite). This system provides... -
Order and disorder in (Mn,Fe)2(P,Si) magnetocaloric compounds
In the high-performance and low-cost (Mn,Fe)2(P,Si) magnetocaloric compounds, the detrimental hysteresis has been significantly reduced by balancing Mn:Fe and P:Si ratios, which... -
Short range static and thermal disorder in glasses and crystals
We seek to use the temperature-dependence of the neutron correlation function to investigate the extent of static disorder in glasses and crystals, and also to investigate the... -
Magnetic excitations in mesoporous hematite
We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One... -
Melting the long-range magnetic order in SrEr2O4 with an applied magnetic field
We have observed an interesting phenomenon of the destruction of long-range magnetic order in SrEr2O4 by a relatively modest applied magnetic field. For a field applied along... -
Quantum magnetism in lanthanide gallium garnet magnetocaloric materials
Geometrically frustrated lanthanide gallium garnets find practical applications as low temperature magnetocalorics, but the competing interactions in these materials may give... -
Magnetoelastic Coupling and for Competing Ground States in (Ba1-xAx)Fe2As2 (A...
Unconventional superconductivity has recently been suggested in the new class of iron-based superconductors in which unusual gap symmetries have been observed together with... -
