The Dynamics of Paraquat in Aqueous Solution and Hydrated Clay
This proposal will enable us to study the dynamics of an important water soluble pesticide molecule, paraquat, in solution and in the interlayer region of swelling... -
Neutron Diffraction study of Highly Frustrated SrEr2O4
We propose to measure the neutron diffraction pattern of a single crystal sample of SrEr2O4, using the WISH diffractometer. As the magnetic Er ions in this compound are linked... -
Characterisation of Spin density Wave phase in Na2Ti2(Sb,As)2O
The formation of charge and spin density wave (CDW and SDW) states in metallic systems isdriven by Fermi surface instabilities that are often found to compete with... -
Powder diffraction determination of the magnetic structure of Ba2LiOsO6
We aim to investigate the antiferromagnetic ground state of Ba2LiOsO6 using neutron powder diffraction, determining both the magnetic ordering propagation vector, and the... -
Multiferroic (Ferroelastic/Magnetic) Phase Transitions in KMnF3
KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling... -
High Resolution Powder Diffraction of Manganites to Determine Bond Lengths as...
Manganites show promise as magnetocaloric materials - for use in solid-state refrigeration - in terms of cost, durability and tunable thermal conductivity. By tuning the... -
Quasi-elastic neutron study of the organic cation dynamics in the halide pero...
Solar cells based on a layer of halide perovskite have recently seen rapid increases in efficiency, with certified values in excess of 20%. The prototypical material of this... -
Dynamical studies of incommensurate spin-density wave order in SrMn1-xWXO3 (X...
Our recent neutron scattering studies on SrMn1-xWXO3 exhibit rich structural and magnetic phases ranging from incommensurate charge (ICDW) and spin (ISDW) density wave... -
Proton dynamics in novel organic ferroelectric materials
The vast majority of known ferroelectrics are inorganic compounds such as barium titanate and potassium dihydrogen phosphate. Contrary to naïve expectation, ferroelectricity in...
