This proposal is part of our research programme on spin and orbital order in frustrated systems. The spinel FeSc2S4 realises an exotic ¿spin-orbital liquid¿ with no magnetic or...

Mononuclear Ni(II) complexes can be designed to behave as two-level systems and thus play the role of qbits with eventually large coherence time. The objective of this proposal...

Thermoelectric materials are increasingly attracting attention due to their potential for use in devices for waste heat energy recovery. Bismuth copper oxychalcogenides have...

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...

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...

Here we propose to investigate the excitation spectrum of the new spin-ladder compound MgCu2O3. Unlike typical spin-ladders this compound has a rung coupling that is much weaker...

This proposal is part of an ongoing project to relate the magnetic excitations to other electronic properties of the cuprate superconductors. We have recently proposed that the...

Quite recently, the high thermoelectric performance has been reported in the MgAgSb-based half Heusler alloys. The ZT values close to 1 at room temperature with a maximum of ZT...

Recent unpublished data collected at MAPS by our group revealed that the spin wave dispersion of the Ba(122) parent differ significantly from Ca(122). In Ba(122) there is a...

The magnetic excitations will be studied in a powdered sample of 3% CoO in 97% MgO in order to to study the excitations of isolated Co ions and of isolated pairs of Co ions....

We have recently shown that acid washing of a carbon support prior to metal (Au, Pd) deposition enhances the activity of the resulting catalysts for the direct synthesis of...

Oxides containing heavy transition-metal ions with four d electrons (d^4) surrounded by an octahedron of oxygen ions have recently been predicted to display a novel type of...

The frustrated quantum magnets could host exotic quantum spin states and have attracted a lot of attention in the past decades. In the system, the degenerate ground states were...

Though NaFeAs shares the same crystallographic structure with LiFeAs, there are many different aspects between them. We would like to compare the magnetic excitation in it with...

The colossal magnetoresistance effect in manganites arises from a competition between delocalisation, which favours a ferromagnetic metallic phase, and localisation of electons...

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...

Geometrically frustrated spin systems are important owing to the fact that the geometry often suppresses conventional mean field ground states in favor of more unconventional...

Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications, having the narrowest ferromagnetic resonance linewidth of any known material. Despite decades...

It has been argued that the tetragonal-to-orthorhombic structural transition found in all the parent phases of the Fe-pnictide superconductors is driven by frustration, and...

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...
