Investigation of the excitation spectrum in the 1D distorted diamond chain Az...
We propose to investigate the excitation spectrum of azurite in both zero field and applied fields up to 7T. Using inelastic neutrons on OSIRIS we hope to clearly resolve the... -
Low energy excitations in solid 4He
The atoms in solid helium are weakly bound and have small mass so that the overlap of their wave functions (zero point motion) is large, making it a quantum solid close to the... -
Quasielastic scattering in stuffed spin ices: defects or low lying singlets?
The subjects of this proposal, Ho2+xTi2-xO7-x/2, are brand new materials1 related to Ho2Ti2O7, a spin ice2,3. They have the remarkable property of remaining disordered at very... -
Spin Frustration in a Novel Molecular FeIII_7 Propeller
The hepta-nuclear Fe(III) title compound Fe7 exhibits a unique antiferromagnetic exchange topology reminiscent of a three-bladed propeller, giving rise to spin frustration, also... -
Experimental evidence for quadrupolar order in the heavy fermion compound Ce3...
This proposal aims to probe the quadrupolar order believed to exist in the heavy fermion compound Ce3Pd20Si6 (CPS). Two phase transitions have been uncovered (in zero applied...
