Thermoelectric materials are increasingly attracting attention due to their potential for use in devices for waste heat energy recovery. Bismuth copper oxychalcogenides have...

We propose to investigate the high-energy (above 10 meV) excitations using either the MERLIN or MAPS chopper instruments. CaFe2O4 is interesting for several reasons. First, it...

We propose to investigate the spin dynamics in the frustrated antiferromagnet beta-CaCr2O4. Its structure consist in one dimensional chains of Cr+3 forming the legs of zig-zag...

We have found unusual and promising Hall effect behaviour in the alloy Fe3Sn2 at 300K. Fe3Sn2 is predominantly ferromagnetic, however, our neutron diffraction data indicate that...

We propose to perform a neutron inelastic scattering study on the anisotropic triangular lattice system beta-NaMnO2. This work will be an extension of our previous study on...

The magnetic excitations will be studied in a powdered sample of 3% CoO in 97% MgO in order to to study the excitations of isolated Co ions and of isolated pairs of Co ions....

We have begun an experimental program to investigate the denaturing of DNA, using scattering techniques, to test statistical mechanical models for the moelcule. It is believed...

We propose to investigate the spin fluctuations in a candidate S=5/2 Kagome lattice. Previous neutron diffraction has found that RbFe2F6 maybe a good realization of a Kagome...

We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One...

Geometrically frustrated spin systems are important owing to the fact that the geometry often suppresses conventional mean field ground states in favor of more unconventional...

We propose to study two single crystals with nominal compositions Fe1.07Te and Fe1.18Te using the MAPS spectrometer. The amount of interstitial Fe controls the material¿s...

The proposal aims to further investigate the transition from commensurate magnetic order to incommensurate magnetic and charge stripe order in the family of compounds,...

The proposal aims to investigate the formation of magnetic stripes in La2-xSrxCoO4. Recent measurements have revealed an hourglass magnetic spectrum at x=1/3. The question we...

We propose to map out the spin excitations in La2O2FeOSe2 using the MARI chopper spectrometer on a powder sample. Although the structure of La2O2FeOSe2 has some similarities to...

We propose to conduct a neutron inelastic scattering study on the CuMnO2 triangular magnet. This material is interesting owing to its possible multiferroic nature. We have...

The proposed experiment is addressed to use the MARI spectrometer to study the thermal denaturation process of the psychrophile enzyme alpha-amylase in presence of bioprotectant...

The proposal addreses the compounds PrPtAl and YbNiSn. Both systems are canted ferromagnets with both materials undergoing moment reorientation transitions as a function of...

Hexagonal iridate Na2IrO3 has recently been proposed as a candidate material to exhibit strong spin-orbit coupling effects which may stabilize a Mott insulating state with...

We propose to carry out inelastic neutron scattering experiments to study magnetic excitation spectrum in FeCrAs. FeCrAs exhibits magnetic ordering around 125 K, which is...

We propose to investigate the high energy magnetic spectrum in Fe1.07Te. We have previously investigated the fluctuations in Fe1.14Te in the incommensurate phase and have found...
