Strong orbital mixing resulting from local distortions in the crystal field can mix higher energy orbital states with the ground state. We propose to characterise this mixing in...

CoFe2O4 is a highly magnetostrictive material with a very high magnetic ordering temperature near 900 K. Preliminary triple-axis work has found sharp acoustic phonons, but...

Neutron scattering techniques at the time-of-flight spectrometers at ISIS have shown that there is a well defined excitation with an energy of about 400 meV in YBCO. A similar...

CaFe2O4 shows an interplay between magnetic structures termed the A and B phases. In this proposal, we request time to measure the spin wave dispersion using MERLIN. Previous...

The proposal requests time to obtain a full mapping of the low-energy acoustic phonons. We have measured an acoustic phonon anomaly associated with the structural transition and...

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

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...

We propose to use muon depth profiling to characterize chemical homogeneity near the surface in a relaxor ferroelectric - PMN. PMN displays a distinct skin effect which may...

CeRhIn5 is an antiferromagnetic itinerant magnet which illustrates a temperature and pressure interplay between antiferromagnetism and superconductivity. Recently, it has been...

Titanite consists of TiO6 octahedra arranged in chains. These are linked by SiO4 tetrahedra. At room temperature, Ti is slightly off-center resulting in an alternation of short...

The proposal deals with understanding the paramagnetic fluctuations in CoV3O8 which have recently been investigated on MARI. This material displays cation disorder and strong...

The '115' phase diagram shows a delicate interplay between strongly correlated magnetism and unconventional superconductivity with similar order parameters to high temperature...

We plan to study the effect of magnetic field on the spin excitations in the newly discovered quantum spin liquid Na2BaCo(PO4)2. Our preliminary inelastic neutron scattering...

RMnAsO (R = Ce and La) are isostructural compounds with Fe-based oxypnictides, but has a unique properties as Mott insulator unlike the nonsuperconducting parent compounds of...

We have been pursuing a study of the magnetic fluctuations in CoO involving a single crystal experiment on MERLIN. To understand the complex magnetic hamiltonian involving...

The proposal aims to measure the powder averaged magnetic excitations in KFe2Se3. The compound is related to the recently discovered Fe-Se,As superconductors and is based upon...

Recent single crystal work on α-CoV2O6 has found a significant enhancement of the nuclear Bragg peaks on entering the low temperature antiferromagnetic states. This...
