Na2PdC2 and Na2PtC2 are the first examples of ternary alkali metal transition metal acetylides. They were synthesized and structurally characterised by our group in 2001 based...

The physical properties of the post-perovskite phase of MgSiO3 control the dynamics of the lower thermal boundary layer of the Earth¿s mantle, but many of these properties...

Sr0.75Y0.25CoO2.62 is a promising cathode material for solid oxide fuel cells. It shows metallic behaviour above 600K and molecular dynamics simulations have concluded that...

We request 4 days on HRPD with the IGAn apparatus to follow the structural changes of Me-ND4 11BD4 as a function of temperature. The high resolution of HRPD will allow us to...

The "magnetocaloric effect" (MCE) is based on the entropy difference encountered when themagnetic state of a material is changed and it can be used for refrigeration. However,...

We have prepared a new non-stoichiometric series Cr2-xInxGe2Te6. X-ray diffraction data can be indexed on the rhombohedral unit cell of the end-member (x=0) phase. This adopts a...

Neutron diffraction experiments will be carried out on multiferroic ceramics. What is special about the measurements, is that they will be carried out under an applied electric...

We propose SANS measurements of 4He in a region of supefluid transition (2.2 K). The main aim of the experiment is to see whether at small-angle scattering there is an...

This experiment will examine the pressure and temeprature phase diagram of the elpasolite perovskite La2NiMnO6. The sample will be studied in the pressure range of 0-9 GPa at...

The dimethylammonium metal formates (metal = Mn, Fe, Co, Ni) are metal-organic perovskite analogues of interest for potential multiferroicity. In these materials, electric...

The object of this proposal is to measure the partial dynamical structure factors and the partial vibrational density of states (VDOS) for the archetypal network forming glass...

In this experiment we will determine the detailed structure of the 6 K superconductor LiFeP and phases close in composition which are iron rich: Li1-xFe1+xP. This will enable...

Pb2FeMO6 phases are of interest as potential multiferroics. We have prepared a new non-centrosymmetric pyrochlore-derived structure containing anion vacancy ordering...

There is considerable interest in understanding the magnetoelectric effect with the aim of developing technological applications. Until recently this has been limited to...

The width of a peak in a pair distribution function (PDF) provides a measure of the variation in the distance between a pair of atoms. This results from a combination of thermal...

New quadruple perovskites with nominal compositions LnFe4Ti3O12 (Ln = La, Nd) have recently been discovered through high pressure synthesis. Mössbauer spectra show that these...

The applicants aim to perform the most authoritative measurements of NCS profiles by controlling and precisely quantifying everything to do with the sample. In July 2008 we...

ReO3 is a well-known oxide framework with unusual thermal expansion behaviour, exhibiting multiple regions of both positive and negative thermal expansion (NTE). We propose to...

The perovskite-like family of ammonium formate frameworks AB(HCO2)3, where A is a divalent metal ion and B is an (alkyl)ammonium or guanadinium, is of great interest for its...
