High Longitudinal Field Relaxation in LiYHoF4
We have observed an anomalous monotonically increasing longitudinal field relaxation rate in LiY_(1-x)Ho_xF_4 for applied fields above 1000 G (along the c-axis) and at a... -
A search for the muoniated hydroxyl radical, OMu
The elusive OMu radical is believed to be formed by muonium reaction with nitrous oxide but has never been directly observed. It would be invisible to transverse-field muon spin... -
Interaction of N2O with Membranes Using µSR
Nitrous oxide, N2O, is an inhalant anaesthetic with a long history of use dating back to 1844. It is most commonly used as a light sedative in dentistry, or in child birth and... -
Study on the dynamical spin equilibrium of (n-C2H5)4N[ZnIIFeIII(C2O3S)3] unde...
The main purpose of this proposed experiment is to investigate the time scale of the dynamical spin equilibrium for the iron(III) site in (n-C2H5)4N[ZnIIFeIII(mto)3] (mto =... -
High Field muSR of Dy2Ti2O7 along [111]: Investigating a partial magnetizatio...
Dy2Ti2O7 is a pyrochlore antiferromagnet that has a partial magnetization plateau between 0.1 and 0.9T for magnetic fields applied along the [111] direction. This represents a... -
Muon Level Crossing Resonance Studies of Anion-exchange Membranes Under Diffe...
Anion-exchange membranes are used in alkaline fuel cells, a technology which allows for the production of power from hydrogen in impure gas streams. Very little is known about... -
Commissioning Proposal ¿ Gas Cell Development
An important element of the work associated with the current Framework Programme 7 Joint Research Activity (JRA) for muons is the development of gas sample pressure cells... -
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... -
New Lifshits magnetic liquid phase in a non-centrosymmetric compound Mn3RhSi
Recently, new phase with Lifshits invariant of incommensurability is reported as a solitonic spin-liquid state above the magnetically ordered phase on Fe1-yTe. It cannot not be... -
Separating static and dynamic contributions to the muon relaxation in Ca3(Co,...
Ca3CoMnO6 has alternating ions in ferromagnetic Ising chains that are antiferromagnetically coupled on a triangular lattice and realizes an important model in frustrated... -
Characterisation of Green-Tea Radical Scavengers by ALC-MuSR and High-Level C...
We propose to characterise selected radical structures of the green-tea anti-oxidant flavenoid EGCG (& selected analogues), by DFT/post-HF computation and ALC-MuSR, towards... -
Does the muon reach thermal equilibrium in a frustrated magnet?
The usual assumption that the muon's polarisation relaxes to zero at long times may be incorrect at high B and low T: for 5T and 30mK the Brillouin function gives P=49%. We plan... -
Level crossings in the open ring molecular magnet Cr8Cd
Molecular nanomagnets (MNMs) comprise clusters of exchange coupled transition metal ions which often have a negative anisotropy constant, favoring a ground state with a large... -
End-Game: Cornering Solvent Effects on H-Addition in Green Tea Anti-Oxidants
Our ongoing project to characterise radical scavenging by the green tea anti-oxidant EGCG and its D-ring analogue, (3,4,5-(OH)3-Bz) is near-complete. ALC-MuSR experiments on the... -

The effect of metal nanoparticles on the electronic structure of bound free r...
In recent years, the noble metals nanoparticles (MNPs) have been the subject of intense interest in areas of materials science, biotechnology, medicine and organic chemistry for... -
ALC studies of solid benzene
For muoniated radical spectroscopy studies, benzene has long been the classic prototype system. However most of these studies have been at higher temperatures, often in the... -
Cyclic Processes in Mid-Range SiGe Alloys
We propose longitudinal muon spin depolarization measurements to extract the energy for the T-site Mu acceptor level in mid-range SiGe alloys where a direct determination of the... -
The role of spin-orbit interaction on Group-III-trisquinolates
Spin based electronics (spintronics) is one of the most exciting and challenging areas in nanotechnology. It is expected to be of major scientific and social impact. Very little... -
Field induced spin Luttinger liquid phase in a spin ladder
Spin ladders present a class of low dimensional quantum magnets that occupy a regime of subtle behaviour which lies between the stark extremes of a one-dimensional chain or...
