A better understanding of the magnetic excitation spectrum of LuFe2O4 is required to refine current models of the magnetoelectric coupling in this novel "electronic"...

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...

We propose to investigate the low energy spin and orbital fluctuations in Bi1.7V8O16 which displays a metal to insulator transition. This work will be performed in conjunction...

NiPS3 is a magnetic material. Its structure has similarities to graphite in that the atoms are strongly bound in planes but the planes are only weakly bound. It is called...

Iron is a canonical instance of an itinerant electron ferromagnet, and a classic correlated electron system. Our recent data from MAPS contradicts earlier triple-axis data that...

Ru4+ ions in Li2RuO3 are on a bipartite lattice and have an orbital degeneracy. The four electrons of the magnetic Ru4+ ions in the threefold-orbitally degenerate t2g manifold...

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...

We propose to investigate the magnetic fluctuations and spin-orbit transitions in Co2V2O7. This material is structurally related to CoV2O6 which displays cascading magnetization...

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

We propose to use MARI to look at the full rotational spectrum of H2 in Ni-MOF-74 obtaining the full momentum distribution for H2 only at the Ni metal site and one with partial...

Several non-centrosymmetric heavy-fermion compounds have been reported to exhibit unconventional superconductivity (SC). For example, both CeRhSi3 and CeIrSi3 order...

In this proposal, we propose to investigate the spin dynamics in the complex material BaFe2Se3. This material presents low dimensional magnetisme below 250K, combined with...

Antimony sulfo-iodide (SbSI) exhibits strongly-coupled photoconductive, semiconducting, and ferroelectric properties. Until the discovery of the lead-oxide ferroelectric relaxor...

We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the...

FeNbSb-related compounds are a group of promising thermoelectric materials. Suppressing the lattice thermal conductivity through different phonon scattering mechanisms could...

At low temperatures FeSi is a non-magnetic insulator, but becomes a metallic paramagnet for T > 300K. It has been proposed to be a Kondo insulator in which local electron...

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...

Compared to carbon nanotubes, metal-oxide imogolite nanotubes (INT), with nominal composition (OH)3Al2O3SixGe1-x(OH), have the peculiarity to have a perfectly defined diameter D...

We will search for spin-orbit transitions of the Co3+ ions in LaCoO3. The ground state is a non-magnetic singlet, but there continues to be a debate about the nature of the...

The Vanadium spinels provide ideal systems to study the interactions between spin, lattice and orbital degrees of freedom. The magnetic V3+ ions are antiferromagnetically...
