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... -
INS studies of conducting polymers: oligothiophenes and polythiophene
Polymeric solar cells are a promising alternative for producing clean and renewable energy due to the possibility of fabricating them onto large areas of lightweight, flexible... -
Low-Temperature Structural Phase Transitions in GeV4S8
The defect thiospinel, GeV4S8 adopts a cubic structure at room temperature (space group F-43m). We have identified a new monoclinic phase of this material at 2K, which may be... -
Search for magnetic correlations in Fe phosphide superconductors
We propose to use inelastic neutron scattering to search for the existence of spin fluctuations in two iron phosphide superconductors, LaFePO and Sr2ScFePO3. The objective is to... -

Characterisation of tunnelling modes of adsorbed methoxy on eta-alumina
Our previous proposal strongly suggested that the methyl groups of adsorbed methoxy on eta-alumina do exhibit tunnelling. This application aims to provide additional evidence to... -
Magnetic study of the new skyrmion-carrying material CoZnMn
Nanoscale magnetic skyrmions are swirl-like magnetisation entities that satisfy topological quantisation conditions. They can therefore not be easily unwound into another... -
Gamma Dopplerimetry to Determine the Environment of Iodine in Halogen Bonded ...
Molecular self-assembly directed by non-covalent interactions presents a unique opportunity to create precisely engineered functional materials. Halogen bonding is a widely... -
Inelastic Neutron Scattering and Raman spectroscopy on 2,2-Paracyclophane
[2,2]-Paracyclophane, C16H16, is a small molecule containing both sp2 and sp3 hybridized carbon atoms. Despite of its apparent simplicity, its solid state structure and... -
Two-dimensional correlation analysis of IINS of water with amino acids.
The interaction of water with biomolecules is of significant interest. To analyse the spectra, we are employing 2D correlation analysis. This has been used extensively with... -
Probing the microscopic origin of polarization in the magnetoelectric R2BaCuO...
We have synthesized the polycrystalline R2BaCuO5 (R = Dy & Ho) and studied its physical properties. Indeed, both the studied compounds exhibit the polarization below rare... -
E/T scaling and quantum critical fluctuations in Sr3Ru2O7
Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature.... -

Study of spin wave and crystal field effect in R2RuO5 (R = Pr, Nd, Tb
R2RuO5 (R = Pr, Nd, Sm, Gd, Tb) are known to exhibit interesting physical properties. They all show magnetic ordering between 8 ¿ 24 K. They also show large Sommerfeld... -
Magnetic structure of the frustrated mixed-valence iridate Ba3LaIr2O9
Mixed-valence iridates are the new platform for studying frustrated magnets and achieving exotic quantum spin liquid ground states. Magnetic interactions in such systems remain... -
Variable Temperature Study of thallium and caesium azides
This proposal seeks to investigate the effect of temperature on the structures of thallium and caesium azide. High-resolution neutron powder diffraction data are necessary to... -
Magnetic ordering in CaFe3O5 and CaFe5O7
This proposal is to explore the evolution of magnetic ordering in two members of the homologous series CaFe2O4(FeO)n with n = 1, & 3, and to correlation the behaviour of the... -
A Self-consistent Description of the Thermoelastic Properties of Dielectric P...
20 years ago, Anderson proposed that the thermoelastic properties of the dominant (mantle) phase within the Earth, MgSiO3 perovskite, could be described as a simple Debye solid.... -
Strain analysis of commensurate charge order/zener polaron ordering transitio...
High resolution powder diffraction data will be used to obtain lattice parameter and atomic coordinate variations as a function of temperature for Pr0.6Ca0.4MnO3, which has a... -
Magnetic and Nuclear Structures of Low-dimensional Antiferromagnet K(1-δ...
In 2010 several groups showed that iron selenide, already a superconductor at 8 K, could be charged with alkali cations leading to higher critical temperatures. These compounds...
