Magnetic excitations of SrV10O15
Recently, new type of frustrated magnets, BaV10O15 and SrV10O15, were found to exhibit interesting phenomena due to mixed valence ions forming a modified triangular lattice.... -
Antiferromagnetic domain manipulation in hematite thin films studied by neutr...
We propose to study the antiferromagnetic (AFM) domain structure of 100 nm thick Fe2O3 thin films using WISH. The sample will be magnetically poled to prepare an imbalance in... -
Investigating the role of oxygen in the mechanism for the transformation from...
Materials for Solid Oxide Fuel Cells (SOFCs) are being developed continuously. Cuprous delafossites (CuBO2 where B=Cu, Cr) are being developed for cathode side applications in... -
The effect of the onset of plastic deformation on texture in cast alpha-uranium.
Crystal plasticity numerical methods are being used increasingly to model the initiation and propagation of fracture in metals. These models can be more critically evaluated... -
Is there electronic nematic order in Fe pnictides?
The concept of an electronic nematic, in which the electronic wavefunctions have different symmetry to the crystal structure, has been proposed to explain several unusual... -
Phonon confinement effects in Si-nanowires
Nanowires can be used for devices based on thermoelectrics and to convert the heat into electrical current. The material design challenge here is to create the materials where... -
Structural Properties of Hydrogenated Ca-Intercalated Graphite Compounds
The recent discovery of superconductivity in Ca-intercalated graphite (C6Ca) has refocused considerable interest onto graphite intercalated compounds (GICs). We would like to... -
Application of direct inversion to magnetic contrast datasets.
We have developed an experimental approach using a buried magnetic layer to provide contrast in systems consisting of complex biomolecular layers tethered to gold surfaces. This... -
Nanostructure of reverse osmosis polymeric membrane for water filtration
Seawater desalination process with reverse osmosis membrane has been widely used to supply high quality water. Over the past decades, despite considerable performance... -
Direct Observation of Gram Negative Bacterial Membrane Disruption by Supramol...
Cyclic peptides with alternating side chain stereochemistry are capable of self-assembling into long nanotubes. The conjugation of polymers to these peptides renders the... -
The mechanism of cuprate superconductivity investigated in CLBLCO single crys...
Although high quality single crystals of cuprate superconductors have been available for quite some time, comparing the properties of different crystals often raised more... -
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... -
Search for magnetic order in a frustrated triangular lattice organic system
This proposal is part of our research programme on novel quantum phases in frustrated lattices. Here we propose to determine the magnetic structure in a quasi-two-dimensional... -
YMnO3-x : Mn(I) in a mixed metal oxide ?
Topotactic reduction of YMnO3 with CaH2 yields three new reduced phases. Two of these phases appear to have compositions close to YMnO2.5 but with very different anion vacancy... -
Polymer-surfactant films containing glucose sensors and structure directing p...
This proposal continues our research on mesostructured surfactant templated polymer films. The films are robust and form spontaneously at the air-water interface. Recent... -
The ferroelectric phase transition in Dion-Jacobson layered perovskites - con...
Ferroelectricity in the Dion-Jacobson (DJ) family of layered perovskites arises from a 'trilinear coupling', whereby two non-polar lattice modes interact in such a way to... -
The exploration of spin waves and magnetic interactions in BaFe12O19
As a member of the large hexagonal ferrite families, M-type barium ferrite BaFe12O19 has been largely investigated by the researchers owing to its rich properties. Recently, a... -
