Defects and monopole dynamics in spin ice
We have determined the defect structure of oxygen-depleted Y2Ti2O7 using diffuse neutron scattering, and we find that these oxygen vacancies are also the dominant defects in... -
Development of thermal microstress and microstrain in polycrystalline zinc: p...
Thermal microstress and microstrain develop in polycrystalline zinc powder particles due to anisotropic thermal expansion, as revealed by corresponding diffraction-line... -
Magnetic Structures of Ni2+ (S = 1) quasi-2D antiferromagnets
Our objective is to determine the magnetic ground state of two isostructural magnetic materials. Both contain nickel(II) ions in octahedral environments, NiX2N4 (where X = Br or... -
Magnetic structure of noncentrosymmetric CeZnAl3
The Ce-based materials CeTX3 (T=transition metal, X= Si, Ge, Al) crystallizing in the noncentrosymmetric BaNiSn3-type structure, have been found to display a wealth of novel... -
Determination of the Crystallographic and Magnetic structures of RbMnBr3, RbF...
We propose to study the crystal structures of RbMnBr3, RbFeBr3 and RbNiBr3 between 300 and 0.3 K. RbMnBr3 under goes two structural phase transition by reducing Rb coordination.... -

Characterisation of Protons in Pyrochlore Electrocatalysts
This proposal is about understanding the atomic-scale structure of complex oxides that contain water or protons and that are used as electrocatalyts for water splitting. Such... -
A detailed study of magnetic diffuse scattering in a low-dimension ferromagne...
We have carried out detailed investigations on the ferromagnetic (FM) Kondo lattice CePdSb, in polycrystal as well as single crystal form (TC=17.5K) using magnetization, neutron... -
4f electronic states of the filled skutterudite compound PrFe4Sb12 synthesize...
Crystals of the filled skutterudite PrFe4Sb12 with the 73~87% Pr-site filling fractions prepared under ambient pressure show some magnetic ordering around 5 K and their... -
Crystal and magnetic structure of the polar ferrimagnet BaCaFe4O7
Polar or non-centrosymmetric ferri(-o)magnets offer a plethora of potential technological devices; the inherent magnetoelectric effect can underpin both pyroelectric or... -
The Local Structure of Doped α - Tricalcium Phosphate
The biomaterial potential of many calcium phosphates, such as hydroxyapatites and tricalcium phosphates (Ca3(PO4)2, TCP hereafter), have led to much literature attention over... -
Proton migration in chromic materials as seen by in-situ simultaneous Neutron...
As part of a facility project aimed at developing a new sample environment allowing simultaneous in-situ neutron diffraction and Raman spectroscopy, we propose to study the... -
The application of INS to investigate the methanol-to-gasoline reaction over ...
We propose to use MERLIN to measure INS from commercial zeolite catalyst samples extracted from a reactor in which they have been exposed to dimethylether for different lengths... -
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... -
Searching for the missing phase of SrTiO3; commissioning a new cryogenic pres...
Generating pressure above 1GPa for neutron diffraction typically requires the use of a Paris-Edinburgh press. Whilst the presses operate very reliably at ambient temperature,... -
Coexistence of Superconductivity and Magnetism in Thin Films
We have recently used a combination of PNR and low energy muon spin rotation (LEM) to detect the coexistence of an induced SDW and superconductivity in the superconducting layer... -
Proton transfer in croconic acid
Croconic acid has recently emerged as the first example of an above room-temperature organic single component ferroelectric. Our goal is to determine its crystal structure at... -
Investigation of magnetic excitations of spin-chain oxides Sr4-xCaxMn2CoO9
The Sr(4-x)Ca(x)Mn2CoO9 compounds are geometrically frustrated transition metal (TM) oxide, which present a variety of interrelated magnetic behavior. The (Mn,Co) TM form a... -
Which is it? ¿ Neutrons distinguish monolayers xrays can¿t.
We have obtained the monolayer structure diffraction patterns from several iodoalkanes adsorbed on graphite, of interest in the study of non-covalent bonding. However, it is... -
Neutron diffraction investigation of magnetic correlations in the S= 1/2 trim...
Spin-trimer chain systems are of current interest due to unconventional properties arising from the strong quantum fluctuations and topology, such as the occurrence of the...
