The proposed experiment will focus on determining the level of texture memory and variant selection on both heating and cooling for steel and titanium and zirconium alloys with...

Ferroelectric tetragonal tungsten bronze oxides (TTBs) have been extensively studied for their application dielectric and non-linear optical devices. TTBs often exhibit...

The aims of the present proposal are twofold. Firstly to use very high resolution neutron diffraction data to establish accurate and precise structures of the novel...

We propose to measure the neutron diffraction pattern of a single crystal sample of SrEr2O4, using the WISH diffractometer. As the magnetic Er ions in this compound are linked...

ACo2As2 (A=Ba, Sr, Ca) are end members of Co doped Ba-122 family. Understanding the magnetic behavior of these end members can help us to understand the magnetic properties of...

TiCl4 forms a molecular structure containing isolated tetrahedral molecules on cooling to 248 K. The freezing pressure of TiCl4 is 0.05 GPa (500 atm). Single crystal growth...

This is a proposal to establish the structural and chemical differences between two phases of composition very close to CaFe3O5 which have been shown by other authors [Hong, K....

4 days are requested on HRPD to collect Neutron Diffraction (ND) on a carefully designed series of (Na1/2Bi1/2)TiO3-based perovskites (NBT) that exhibit a switch in electrical...

Vanadium based compounds have attracted considerable interest as positive electrode materials for Li ion batteries. This is due to vanadium’s ability to display a range of...

Tetragonal R(Fe,M)12 compounds (R=rare earth, M transition metal or Si), with the ThMn12 structure, are good candidates as permanent magnet materials with reduced R content....

There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap and safe cathodes. Recently, silicate-based cathodes have been described,...

It is proposed that the lattice parameter change at high temperature is measured for a mix of 316L and SA508 grade 3 steel powders, by means of neutron diffraction in High...

We request three days of beam-time on POLARIS to investigate the influence of thermally-induced twinning on the thermal expansion behaviour of polycrystalline calcite....

Modulation has been understood and used to explain physical properties in solid-state materials for many years. Molecular modulated structures relatively scarce, but due to...

The aim of this experiment is to complete the understanding of the complex nature of the structural and magnetic interactions in the La0.7Sr0.3Mn1-xFexO3 series of materials in...

We propose to study the effect of pressure and temperature on the crystal structure and the elastic properties of lead selenide, an important material for conversion of waste...

the correlation degree in 122 iron pnictides mainly depends on the electronoccupancy of each orbital and that by doping electrons the correlation decreases monotonically. This...

Thermoelectric devices are capable of converting thermal energy directly into electrical energy. The efficiency of a device is related to the characteristics of the materials of...

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...

Overdoped manganites were recently shown to exhibit stripe-like ordering of charges orbitals and magnetic moments. The magnetic excitations in these materials show close...
