This proposal is part of our research programme to explore novel phases stabilized by the combined effect of spin-orbit interaction and electron correlations. Here we aim to...

This proposal requests time to investigate the influence of an applied magnetic field on the oxyselenide Pr2O2Fe2OSe2. A metamagnetic transition involving ordering of Pr3+...

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...

The exotic physics of low-dimensional quantum magnets has recently been highlighted by the award of a Nobel Prize to Duncan Haldane. We have identified the molecular framework...

The electronic dispersion of "Dirac" materials such as graphene and topological insulators is linear, resulting in a variety of peculiar electronic properties. In graphene and...

Ferroelectricity in type-II multiferroics is induced by breaking of inversion symmetry by certain type of spin structure below the magnetic ordering temperature. Therefore, a...

In recent years there has been a large interest in geometrically frustrated magnetic systems, especially those with spins interacting on two-dimensional triangular lattices...

Recently we have investigated magnetic and quadrupolar ordered states of YbRu2Ge2 using zero-field muon spin relaxation (µSR), neutron diffraction and inelastic neutron...

We had been given 1 day of beam time on WISH, RB1710144, to investigate the magnetic structure of T2V2O7 (T=Mn, Ni, Co) We performed power neutron diffraction measurements on...

Both 1D physics (dimensional frustration) and geometric frustration offer ways of achieving unusual quantum ground states that defy the usual tendency for systems to order at...

We propose to perform neutron diffraction experiments on single crystals, 3R-AgFeO2 and 2H-AgFeO2 on WISH. Recently, we have studied magnetic orderings and ferroelectricity of...

New layered perovskite compounds LaBaFeMnO5 and LaBaFeMnO6 were recently synthesized. They may be useful for future oxygen storage applications. Fe-Mössbauer spectroscopy has...

Manganese based oxides are of great interest for both spintronic and multiferroic applications.Pb2MnO4 crystallizes in the acentric but non-polar space group P-421c which...

The layered compound Na2Co2TeO6 is a model honeycomb compound having a zigzag antiferromagnetic (AFM) ground state. Na2Co2TeO6 poses a rich magnetic phase diagram in the H-T...

Purely ferromagnetic (FM) oxides are uncommon but we recently reported FM behaviour in a mineral induced by quite small magnetic fields. This ability relates to the presence of...

We propose using WISH and HRPD to examine the structure of the Ba1-xNaxTi2Sb2O phase diagram as a function of temperature. The primary goals are the determination of the...

Three new doubly ordered perovskites NaYMWO6 (M=Mn, Co & Ni) have been synthesized by high pressure and high temperature. Analysis of room temperature laboratory X-ray...

The coupling between magnetic and electric degrees of freedom, in a single phase compound has been of intense research in recent literature, as the outcome would yield novel...

We propose to study by powder neutron diffraction the ordered magnetic state of the pyrochlore compound Y2Ir2O7. There is currently an increasing interest in the condensed...
