Study of frustration and the anomalous Hall effect in Fe3Sn2
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... -
Spin fluctuations in the triangular antiferromagnet beta-NaMnO2
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... -
Magnetic Excitations of Isolated and Pairs of Co Ions and in MgO
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.... -
Spin excitations in RbFe2F6 ¿ A possible S=5/2 Kagome lattice?
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... -
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... -

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... -
Spin excitations in La2O2Fe2OSe2 ¿ A Mott insulator candidate
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... -
Low-energy magnetic dynamics in the triangular lattice CuMnO2
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... -
Understanding the ground state wavefunction in PrPtAl and YbNiSn
The proposal addreses the compounds PrPtAl and YbNiSn. Both systems are canted ferromagnets with both materials undergoing moment reorientation transitions as a function of... -
Magnetic excitations in FeCrAs
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...
