It has recently been discovered than the rutile phase of zinc fluoride shows negative thermal expansion along all three crystallographic axes. What is highly unusual about this...

Several distinct families of layered perovskites have been shown experimentally to display ferroelectricity. The most recent of these is the Dion-Jacobson (DJ) family, typified...

The vast majority of known ferroelectrics are inorganic compounds such as barium titanate and potassium dihydrogen phosphate. Contrary to naïve expectation, ferroelectricity in...

We propose the investigation of the magnetic structure in the room temperature magnet SrRu2O6 and its doped variants. Crystallizing in the honeycomb structure, these systems are...

Iron tungstate Fe2WO6 attracts increasing interest in two areas of applications due to its photoelectrochemical behaviour. Fe2WO6 can act either as a photocatalyst for...

KFe0.8Ag1.2Te2 is made of 2x2 squares of Fe atoms, upon lowering temperature the system spontaneously undergoes a transition that breaks the fourfold rotational symmetry. A...

We propose to make use of neutron wave guiding effects to enhance interfacial sensitivity and study the spin texture of individual interfaces between ferromagnetically doped...

This is an experiment to probe the magnetic ordering in Ba2CrO2Cr2As2 and compare the behaviour with the Sr analogue which shows a complex spin reorientation transition around...

Perovskite zirconates have been suggested as potential next generation thermal barrier materials. SrZrO3 is particularly promising as it has an extremely low thermal...

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....

We propose to obtain 3 days of beam time on SXD equipped with its new top-loading CCR to analyze CaCrFe3As3 single crystals at different temperatures 10 K, 100 K and 300 K (the...

In this proposal we request 3 days of beam time on HRPD to study the structures (both atomic and magnetic) of a variety of oxychalcogenide phases: La2O2Se2Fe2O, Ce2O2Se2Mn and...

The organic-inorganic perovskites (CH3NH3Pb(Br,Cl,I)3) have been identified as efficient photovoltaic materials. Theoretical calculations have suggested that the low energy...

Transition metal oxynitride perovskites are an emerging class of functional materials. However, their oxide/nitride ordering principles were unclear until a recent study of the...

Solar cells based on a layer of halide perovskite have recently seen rapid increases in efficiency, with certified values in excess of 20%. The prototypical material of this...

The study of porous metal-organic framework (MOF) materials has attracted considerable attention. We seek to develop new stable MOFs for practical gas separation and request 3...

The purpose of this investigation is to investigate the electric field dependence of the dynamics of the melting transition of bulk and confined water with an applied electric...

Manganites show promise as magnetocaloric materials - for use in solid-state refrigeration - in terms of cost, durability and tunable thermal conductivity. By tuning the...

Despite the importance of the LiFeO2 phases as cathode materials in lithium ion batteries, little is known about their crystal structures, except that they should be based on...

Hydrogen is an efficient energy carrier that can be produced from renewable sources and stored in alloys in solid-state for long period enabling the transition towards CO2-free...
