This study is designed to identify relationships between structure and magnetic properties characteristic of coordination polymers (CPs). By determining the ground state 3D...

Understanding the magnetic structure of the perovskite manganites has been a significant field of research over the past 20 year due of their numerous technologically relevant...

The NH4M(formate)3 (M = Mn, Fe, Co and Ni) series are the most promising members of a new family of multiferroics in which ferroelectric ordering is driven by hydrogen-bonding...

Preliminary bulk measurements show that Ba(TiO)Cu4(PO4)4 is a potentially exciting candidate for studies of low-dimensional magnetism. However, currently relatively little is...

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

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...

Materials with antiferromagnetic interactions between spins on a triangle lattice inherently exhibit large frustration between similar energy ground states giving rise to novel...

Unconventional superconductivity has recently been suggested in the new class of iron-based superconductors in which unusual gap symmetries have been observed together with...

Zeolites are porous crystals that make it possible to generate regularly arrayed alkali-metal nanoclusters. Potassium clusters arrayed in zeolite A show ferromagnetism below 7 K...

The experimental realization of a S=1/2 kagome lattice has been one of the holy grail of frustrated magnetism because when all antiferromagnetic exchanges cannot be satisfied, a...

There is a growing need to reduce dependence on liquid He for cooling applications below 20 K. Magnetocalorics, which exhibit an entropically driven cooling effect in a cycled...

The late first row transition metal monoxides are the canonical antiferromagnets. Their magnetic structures were first determined many decades ago but contemporary studies have...

With fantastic flux gains over its liquid conterpart, a solid methane moderator is essential to the newly built Second Target Station at ISIS. Unfortunately, it is notoriously...

Osmates in the perovskite-like structure are very topical. For example, recent discoveries include Slater transitions, and "ferroelectric-like" structural transitions. These...

Antiferromagnetic S = 1 one-dimensional chains exhibit a myriad of magnetic ground states depending on the balance between the spin exchange parameter and the single-ion...

Ba2CuTeO6 is a newly discovered S=1/2 spin ladder system containing Cu2+ ladders. Our experiments indicate that this material is in very close proximity to the quantum critical...

We have recently discovered a new family of geometric frustrated magnets starting from the parent system, RbFe2F6, with crystallizes in the defect or β-pyrochlore structure...

Ba4Ru3O10 is a rather fascinating compound with quasi two dimensional crystal structure. Although the compound shows strong feature in the magnetization data at 105 K indicating...

CuFeO2 is a geometrically frustrated triangular lattice system. At low temperatures it shows a number of different spin orders with applied magnetic field. CuFeO2 also has a...

Our aim is to study with high resolution neutron powder diffraction the two orthorhombic phases of Mn2TeO6 at RT, so as to understand the origin of the observed structural...
