This proposal is part of our project to investigate the unusual physics of 5d transition metal oxides. In particular, we are studying two samples of the chemical composition...

In a previous experiment we measured the spin wave spectrum of the half-doped bilayer manganite Pr(Ca,Sr)2Mn2O7 in its spin, charge and orbital ordered phase. The data, which...

Spinel oxides with the formula AB2O4, are an important structural family of materials which exhibit a large variety of interesting and industrially relevant properties. We have...

We propose an investigation of the spin-waves in the recently discovered room-temperature skyrmion material Co8Zn8Mn4. The ground state of Co8Zn8Mn4 is a very long wavelength...

This is a proposal to measure the magnetic spectrum of single crystal La2-xBaxCoO4 for the first time. The isostructural layered cobaltates with Sr and Ca instead of Ba have...

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...

The aim of our experiment is to map out the excitation spectrum of the recently-discovered superconducting AxFe2Se2 system for energy transfers of up to 250 meV. This...

This is a proposal to fully characterise the crystal structures of new, ammonia-rich electropositive metal/ammonia intercalates of iron selenide which are in equilibrium with...

The formation of charge and spin density wave (CDW and SDW) states in metallic systems isdriven by Fermi surface instabilities that are often found to compete with...

We propose to measure the high energy magnetic dispersion of CuO. At high energies, CuO exhibits quasi-1D spin-1/2 chain magnetic behaviour. Our previous studies have revealed...

Iridium oxides are of interest because many novel magnetic phases have been predicted in crystals, depending on the geometry of the crystal lattice. Our proposal concerns two...

This proposal is part of a project in which we explore the unusual physics of 5d transition metal oxides. Using a special high pressure technique, we have synthesised first...

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...

NaxCoO2 has an exceptional combination of thermoelectric properties, including low thermal conductivity, and it is currently under consideration for use in power recovery and as...

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

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...

Rare-earth Iron garnets (R3Fe5O12) have been in the focus of active research for the last five decades due to properties such as magnetostriction, magneto-optical effects, as...

In our first measurement of the high energy spectrum of LaCoO3 we observed a signal which is a promising candidate for an electronic transition from the low spin ground state of...

We have synthesized a new cobalte oxide compound. We know from preliminary measurements that its crystal structure is hexagonal, and that the magnetic behaviour is intriguing....

We propose to use inelastic neutron scattering to search for the existence of spin fluctuations in two iron phosphide superconductors, LaFePO and Sr2ScFePO3. The objective is to...
