Skyrmion phase dynamics in the beta-Mn-type system Co8Zn8Mn4
Skyrmions are topological objects which have been shown to exist in the spin textures of a range of magnetic materials. As we have recently demonstrated in our transverse field... -
Thermoelastic properties of ammonium sulfate, (ND4)2SO4, and the P-T dependen...
Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crystal. There have been no... -
Magnetic ordering in AgFBF4 a nearly perfect 1D AFM with huge intra-chain c...
We propose to investigate AgFBF4, a compound known for > 20 years, with muon spectroscopy. The scope is to determine the 3D ordering temperature as well as estimate the value... -
Anisotropic Li+ diffusion in the cathode material LiFePO4
LiFePO4 is cathode material for Li ion batteries. One of the key functional properties is the Li-ion diffusion. Theoretical calculations showed that Li diffusion along the [010]... -
Probing the glass transition in polymers using LF muSR
Nearly all polymers form glasses and the glass transition at temperature Tg dominates many physical properties of polymers that are relevant for their applications. The most... -
LF and RF muSR Studies of Polymer Dynamics in Polydimethylsiloxane
Muon spin relaxation will be used to study the dynamical properties of the polymer polydimethylsiloxane. This has emerged as an excellent model system for the study of polymer... -

Is there magnetic order in intrinsically frustrated rare earth bilayer alumin...
Compounds with formula R2SrAl2O7 (R=rare earth) look superficially similar to the well-known bilayer manganites, but here the perovskite bilayers contain Al and are nonmagnetic.... -
Non-equilibrium effects in the skyrmion material Co8Zn8Mn4
Skyrmions are topologically protected, vortex-like nano-sized objects which have been shown to exist in the spin textures of a range of magnetic materials. As we have recently... -
Probing the interplay between charge density wave and superconductivity in st...
We propose to study PdxIrTe2, which evolves from a charge-orbital density wave state to a superconducting state with doping. It has a similar structural motif, doping-dependent... -
Spin Frustration in Iridate Systems, and the Role of the Spin-Orbit Coupling
We propose to investigate the roles of the spin-orbit interaction and geometrical frustration in stabilising a quantum spin liquid phase (QSL) in some iridate systems. µSR is a... -
Muonium in rare-earth sesquioxides
We propose to characterize the basic muonium/hydrogen configurations in selected rare-earth sesquioxides with the basic crystallographic structures: neodymium oxide (hexagonal A... -
Structure and magnetic properties of Sr4Fe6O12
Despite many previous attempts, Sr4Fe6O12 (the expected fully reduced composition for Sr4Fe6O13-x) has not been synthesised. It is of interest because it is believed to contain... -
Probing glassy magnetic transitions in structurally disordered (defect fluori...
Cubic A2B2O7 oxides with A standing for a rare-earth element and B for a transition or main block metal have been systematically studied for their frequently exotic... -
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... -
Well, well, well: the free energy landscape of hydrogenated La(Fe,Si)13?
Magnetic cooling promises efficiency savings at room temperature but requires rapid cycling of a magnetic refrigerant in a magnetic field. Refrigerants with first order... -
Li+ Diffusion Behaviour of Activated Carbon-treated Li4Ti5O12
We propose to carry out muon-spin relaxation to examine Li+ diffusion in AC-treated Li4Ti5O12 which contains a small amount of rutile TiO2. Measurements will be carried out over... -
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... -
