The effect of a vanishing pseudogap on the magnetic excitations in overdoped ...
One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution... -
Investigation of the structural and magnetic properties of new Co based fluor...
We have recently managed to prepare powder samples and small single crystals of BaCoF4, BaNiF4, Ba2Co3F10, and the new tetragonal compound Ba2CoF6. These materials are... -
Magnetoelastic coupling effect on multiferroic behaviors in different types o...
We propose to perform high resolution neutron diffraction on powder samples of the frustrated antiferromagnets Ag1-xCuxFe1-yGayO2 using HRPD. CuFe1-yGayO2 and AgFeO2 have... -

Neutron Diffraction Study of a Spin-1/2 Pyrochlore Lu2Mo2O5N2
Ammonolysis of R2Mo2O7 pyrochlores gives R2Mo2O5N2 containing S = ½ Mo5+. They are excellent candidate materials for investigation of quantum spin liquid phenomena and we have... -
Melting the long-range magnetic order in SrEr2O4 with an applied magnetic field
We have observed an interesting phenomenon of the destruction of long-range magnetic order in SrEr2O4 by a relatively modest applied magnetic field. For a field applied along... -
Determining the Crystal and Magnetic Structures of [Li(oxalate)]2[Co5(OH)8]
Dense corrdination frameworks that contain inorganic centres connected into extended lattices by polyatomic anions often adopt highly anisotropic structures. Thus they often... -
The Dynamics of Molecular Hydrogen in Synthetic Clays
In this proposal we aim to study the low temperature uptake and dynamics of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual... -

Fishing for a new magnetic phase in the Pr1-xCaxMnO3 manganites phase diagram
Based on old data and the recent litterature, we suspect the existence of a poorly documented low temperature magnetic phase transition (T<30K) in colossal magnetoresitve... -
Unusual higher order incommensurate components in the magnetic structure of TmCu
This proposal forms a very specific part of our project to investigate complex magnetic structures in rare earth intermetallics. In extensive bulk measurements on high purity... -
Uniaxial pressure induced spin-density wave order in CeAuSb2
We propose to apply uniaxial strain to induce a spin-density wave (SDW) modulation in CeAuSb2. Neutron diffraction measurements show this system has a tendency to order along... -

Hydrogen dynamics in clay nanotubes
We will study H2 dynamics in the nanotubular clay imogolite whose structure has an external diameter of ~2.5 nm and an inner diameter of <1 nm. The tube length of synthetic... -
The Structure of the High-Energy ¿Paramagnon¿ Excitations in La2-xSrxCuO4
A major problem in physics is the identification of the mechanism of high-temperature superconductivity. Many theories purport to explain the high-Tc phenomenon. In most... -
Partially disordered antiferromagnet phase of CsCoX3 (X=Cl, Br)
Systems of the CsCoX3 family form antiferromagnetic chains along the c-axis, and are arranged in a frustrated triangular arrangement in the ab-plane. Below 30K, both systems... -
