KFe0.8Ag1.2Te2 is made of 2x2 squares of Fe atoms, upon lowering temperature the system spontaneously undergoes a transition that breaks the fourfold rotational symmetry. A...

The rare earth iridates, R2Ir2O7 have been intensely studied in recent years due to the unique behaviour of the magnetism on the iridium sites; a consequence of competition...

We propose to measure the powder-averaged spin excitation spectrum of LiFeAs, a new member of the ferropnictide family of superconductors. This compound is special because it is...

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

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...

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...

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...

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...

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

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...

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

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...

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

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...

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

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...

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...

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...

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...
