The layered NaMnO2 is challenging as it is an experimental realization of a two-dimensional spin-2, spatially anisotropic triangular lattice, where the interplay of temperature...

Polaron-mediated colossal magneto-resistance (CMR) was predicted decades ago but never been experimentally established unambigously, despite the 'universal' existence of...

We propose to use a pulsed magnet system tried and tested at several neutron and synchrotron facilities in conjunction with the new high flux diffractometer WISH to perform the...

We propose a study of the low temperature magnetic structure of vanadium dioxide (VO2) compounds using long-wavelength neutron diffraction measurements. This study directly...

We propose to use WISH to characterise magnetic order of a new quantum (S=1/2) geometrically frustrated material based on the mineral averievite, Cu_5(VO_4)_2O_2CsCl. This...

TbMnO3 attracts special attention due to its large magnetoelectric coupling, polarization flop and ferro-paramagnetic phase transition, both induced by magnetic field. Despite...

This proposal forms part of our project to investigate the implications of non-trivial real-space topology in multi-k magnetic structures. We are here focusing on the rare earth...

Magnetic and orbital ordering in the manganese based perovskites has been of huge interest in solid-state physics since the 1950's. More recently, the family of AA′3Mn4O12...

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...

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...

Magnetic nanoparticles are currently being investigated comprehensively. Our ball-milled TbCu2 nanoparticles show a core-shell structure in which the core orders...

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 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...

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 experiment under high pressure condition, using a single crystal of CuO on WISH beamline. This monoxide is known as a multiferroic...

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...

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

Ferroelectricity induced by magnetic ordering with certain type of magnetic structure has received much attention because it provides opportunity to manipulate magnetization by...

The spin Jahn-Teller effect stabilises 3D magnetic order in an otherwise frustrated system via magnetoelastic coupling, spontaneously at the magnetic phase transition. Examples...

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