Electronic state of Co3+ in LaCoO3
We will search for spin-orbit transitions of the Co3+ ions in LaCoO3. The ground state is a non-magnetic singlet, but there continues to be a debate about the nature of the... -
Spin-orbit transitions of Co3+ in LaCoO3
In our first measurement of the high energy spectrum of LaCoO3 we observed a signal which is a promising candidate for an electronic transition from the low spin ground state of... -
Magnetic Excitations in 50% Cu substituted BaFe2-xCuxAs2
We find unusual antiferromagnetic order in Cu heavily overdoped BaFeCuAs2 with the order wave vector at (0.5 0.5 1). This anitiferromagnetic signal cannot come from the parent... -

Magnetic excitations in a pure Fe3+ pyrochlore lattice (FeF3) ¿ A classic spi...
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... -
Dynamics of Confined CO2
This proposal aims to investigate and compare the dynamics of CO2 when confined in a nanoporous Vycor (SiO2) matrix. The field of fluids in confined geometries is currently of... -
Magnetic excitations in mesoporous hematite
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... -
Spin and orbital fluctuations in MgV2O4
We propose to the measure the spin and orbital fluctuations associated with Vanadium in MgV2O4 using the MAPS direct geometry chopper spectrometer. This proposal will use the...
