Muon spin relaxation studies of KTCNQ and related compounds
Potassium tetracyanoquinodimenthane (KTCNQ) undergoes a spin-Peierls (SP) transition at 396K where a transformation from uniform to dimerised TCNQ- molecules in 1D columns... -
Chemical control of structures and properties of layered oxide chalcogenides
The crystal structures and magnetic ordering of layered compounds that have been modified by low temperature chemical methods will be probed using neutrons. The systems... -
Using muons to investigate the excitation spectrum in low-dimensional molecul...
We propose to use longitudinal field muon-spin relaxation to investigate the excitation spectrum of the most successful realizations of one- and two-dimensional antiferromagnets... -
Probing superconductivity, static magnetism and light ion diffusion in molecu...
In 2012 we demonstrated that molecular spacer layers could be intercalated in between FeSe layers resulting in a dramatic enhancement of the critical temperature: FeSe is itself... -
Field-induced low-temperature magnetic phase in alkali-metal sesquioxides
Open p-shell anionic compounds are model systems where the interplay between charge, lattice, orbital, and spin degrees of freedom leads to complex magnetic behavior. In the... -
Dynamics of the quasi-two dimensional XXZ honeycomb antiferromagnet BaNi2V2O8
We propose to perform zero-field muon spin rotation studies of S=1 honeycomb antiferromagnet BaNi2V2O8 which is an ideal physical realization of the quasi-2D magnetic system.... -
HIGH RESOLUTION NEUTRON DIFFRACTION STUDIES ON NEW POLYMORPHS OF MAGENSIUM TE...
The development of high energy density and high efficiency hydrogen storage materials is widely considered to be one of the most challenging barriers to the adoption of fuel... -
Local Field fluctuations and Mu Dynamics in Vanadium Dioxide Compounds
This is an in depth study of magnetic fluctuations and local field dynamics leading into the low temperature magnetic phase of Vanadium Oxide compounds (VO2, VO2:W and VO2:Ti)... -
Spectroscopy of muon centres in n-type silicon carbide
We propose to continue laser spectroscopy measurements of the muonium (Mu-) centres in n-type doped silicon carbide. Scanning a wide wavelength range, and changing the relative... -
An ALC study of the organic ferroelectrics TTF-CA and TTF-BA
The study of organic ferroelectrics based on mixed-stack charge-transfer salts is currently a rapidly developing research field. These materials attract interest as highly... -
Oxygen deficiency in the quantum spin ice Tb2Ti2O7
Tb2Ti2O7 is one of two compounds identified as potential quantum spin ices. As with other oxide pyrochlores the properties depend sensitively on the oxygen content. Most... -
muSR study of the charge ordered phase of RbFe2As2 iron based superconductor
We propose to study the evolution of ZF-muSR and low-field (100 G) TF-muSR spectra and relaxation times across the charge ordering temperature T0 = 140 K of RbFe2As2 iron based... -
Direct measurement of magnetoelectric coupling - a new room temperature multi...
We have recently performed muon measurements on a member of a new class of multiferroic materials. We have shown that there is hysteretic behaviour to the internal field... -
Investigation of muonium diffusion, states and charge cycles in vanadium dioxide
We propose a study to characterize diffusive motion of muonium, charge cycles and Mu0 states in vanadium dioxide (VO2) using zero and longitudinal field muon spin depolarization... -

Li diffusion in charged state Lix(Ni1/3Co1/3Mn1/3)O2
This proposal describes a muSR experiment on Li-deficient Lix(Ni1/3Co1/3Mn1/3)O2 to determine a Li diffusion coefficient as a function of the Li content x, because muSR is a... -
Probing the carrier-induced donor-to-acceptor transition of muonium in indium...
The first experiment we propose is a search for a shallow-donor signal for muonium in indium oxide. Its observation would test our assertion, based on our measurements of... -
A µSR study of single crystals of the superconductor FeSe1 xTex (0≤x...
Superconductivity was recently discovered in alpha-phase FeSex with a Tc of 8 K. Selenium can be replaced with Tellurium (FeSe1-xTex) and this results in an increase in Tc to 15... -
Probing the Magnetism and Suspected Quantum Fluctuations in Green Dioptase
It has been suggested that within green dipotase there the magnetism is dominated by quantum flucuations but evidence for this is not definitive. This means that in this... -
Spin dynamics and magnetic ordering in the p-orbital molecular solids CsO2 an...
A magnetic response of the alkali-metal superoxides comes from the p-orbital S = 1/2 spins of anionic O2- molecules. As the O2- molecules are highly reorientable and the...
