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 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 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...

We propose to study the powder averaged spin fluctuations in a S=5/2 pryochlore - FeF3. Previous studies, corroborated by our own diffraction work on WISH, have measured that...

LiFeAs is one of the newly discovered FeAs superconductors with still large T_c of 18K. First inelastic neutron scattering experiments on powder and on single-crystalline...

The unique "hourglass"-type dispersion observed within several classes of hole-doped cuprates has garnered considerable theoretical and experimental interest. Here we propose to...

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

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...
