Motion of Positevely Charged Muonium Centres in Transparent Conducting Oxides
A continued study of muonium diffusion in transparent conducting oxides (TCO) are proposed. We have ZF depolarization measurements conducted up to room temperatures for SnO2 and... -
Spin exchange interactions and fractionalized spin excitations in the geometr...
The recently discovered new triangular lattice QSL candidate YbMgGaO4 has attracted great interest on rare earth frustrated magnets. Another triangular lattice rare earth... -
Fractionalized excitations in the zigzag pseudospin-1/2 quantum chain compoun...
One-dimensional (1D) S = 1/2 spin chains are a subject of long-standing interest, because conventional long-range ordering can be prevented and novel Luttinger-liquid phase may... -
Thermal ionization of bond-centred muonium in diamond
Our previous LF-µSR measurements in natural type Ia single crystal diamond showed some evidence of the ionization of bond-centred muonium (MuBC) from around 1000K. This was... -
The role of spin fluctuations, disorder and non-colinearity in the INVAR effect
The origin of the Invar effect, whereby certain ferromagnetic alloys exhibit near zero thermal expansion around room temperature is still not properly understood. Although the... -
In-Situ Studies of Electrochemically Enhanced Performance in Perovskite Elect...
Recent studies in our laboratory have shown that a range of A-site deficient perovskite oxides, with carefully tuned chemical compositions, exhibit excellent properties when... -
Structural origin of negative thermal expansion in ScF3
Scandium fluoride has recently been identified as a very simple example of a material showing negative thermal expansion over a wide range of temperatures. In particular, it... -
The First Structural Characterisation of some Gallium Oxide Polymorphs
We propose to make the first detailed structural study of some polymorphs of gallium oxide that remain poorly characterised and yet have applications in catalysis and are used... -
In situ neutron diffraction study of Sr0.75Y0.25CoO2.62
Sr0.75Y0.25CoO2.62 is a promising cathode material for solid oxide fuel cells. It shows metallic behaviour above 600K and molecular dynamics simulations have concluded that... -
Investigation of Magnetic Fields in ZnGeP2:Mn
We propose an investigation of the magnitude and fluctuations of internal magnetic fields in Mn-doped ZnGeP2. This chalcopyrite structured semiconductor has a ferromagnetic (FM)... -
Motion of Positively Charged Muonium Centres in Transparent Conducting Oxides
We propose further zero-field muon spin depolarization measurements at temperatures above 300K in order to determine barriers for thermal diffusion of positively charged muonium... -
Magnetic properties of Graphene
This year Nobel Prize award to the discovery of graphene has evidenced the relevance of this material, which has outstanding physical properties and promising technological... -
Spin dynamics of the Heisenberg triangular antiferromagnet KCrO2
The members of the series ACrO2 (where A=Li, Na, K) comprise well-decoupled, highly ideal triangular planes containing isotropic spins. While the A=Li and Na materials have been... -
The ferroelectric phase transition in Dion-Jacobson layered perovskites
Several distinct families of layered perovskites have been shown experimentally to display ferroelectricity. The most recent of these is the Dion-Jacobson (DJ) family, typified...
