Water Binding and Solvent Dynamics in Natural Deep Eutectic Solvents
Deep Eutectic Solvents (DES) are molecular mixtures similar to ionic liquids, having melting points below room temperature. However instead of being composed of a salt, the... -
The effect of a vanishing pseudogap on the magnetic excitations in overdoped ...
One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution... -
Magnetic excitations in honeycomb ruthenate Na2RuO3
Honeycomb magnets with strong spin-orbit coupling (SOC) are expect to produce exotic magnetic ground states as exemplified by d5 iridates with Jeff = 1/2 state. In d4 case, SOC... -
Examining magnetic correlations and dynamics in the metallic non-collinear an...
Non-collinear antiferromagnets are currently an area of much active research due to their potential use in creating robust spintronic and spin memory devices. We have recently... -
Structure-Property Relationships in Oxide Ion Conductors: Bi6WO12
High temperature Bi2O3 has the highest oxide ion conductivity known for any material. It has an oxygen-deficient fluorite-based structure, with 25% of oxygen atoms missing from... -
High-Energy dynamics and search for a continuum in CaFe2O4
We propose to investigate the high-energy (above 10 meV) excitations using either the MERLIN or MAPS chopper instruments. CaFe2O4 is interesting for several reasons. First, it... -
High precision measurement of the spin waves in Yttrium Iron Garnet
Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications. It is a ferrimagnetic spinel with the narrowest ferromagnetic resonance linewidth of any known... -

The weakly coupled spin cluster systems provide a fertile ground to study both zero-dimensional quantum and three-dimensional collective magnetism. Such spin cluster systems... -
Spin orders in CaxMn2-xFeReO6 double perovskites
New manganese-based double perovskites Mn2-xCaxFeReO6 have been synthesised at high pressure. Mn2FeReO6 has spin-active cations at all sites; S = 5/2 Mn2+, S = 5/2 Fe3+ and S =... -
Giant spin fluctuations and their effect on the first order magnetic transiti...
A giant enhancement of the heat capacity in La(Fe13-xSix) indicates the presence of large spin fluctuations at the paramagnetic to ferromagnetic phase transition. The nature of... -
Pressure effect on stable and metastable structural phases in geometrically f...
Geometrically frustrated antiferromagnet LuBaCo4O7 exhibits unusual competition between two low-temperature phases with orthorhombic and monoclinic symmetry. Depending on... -

Magnetic Profile of a Novel Magnetic Quantum Well
Proximity effects associated with magnetic impurities embedded in paramagnetic Pd have been known to produced so-called giant moments. It has been demonstrated that confining Fe... -
How does a catalyst promoter affect the degree of hydrogen retention of iron-...
We have recently used INS to determine how a hydrogen pre-treatment stage of an iron based Fischer-Tropsch catalyst may modify catalytic performance. That work established how... -
The Active Site in Iron Molybdate Catalysts for Selective Methanol Oxidation
Formaldehyde is an industrially important chemical (world production 32 million tonnes in 2006) currently made from methanol using an iron molybdate catalyst. Reaction occurs at... -
Some Ferroic Perovskite Solid Solutions
We are examining various perovskite solid solutions based on NaNbO3 or BiFeO3 that havepromising ferroelectric or multiferroic properties. All of these solid solutions show... -
