Vesignieite, Cu3VBa2O8(OH)2, is one of very few materials approximating a kagome spin-1/2 Heisenberg antiferromagnet, a model that is the ideal setting for novel quantum spin...

We aim to explore the groundstate of a new near-perfect S=1/2 kagome antiferromagnetic (KAFM) system using MuSR at the lowest possible temperatures. The title compound is...

Small-sized metal nanoparticles (NPs) are of long standing interest to both magnetism and heterogeneous catalysis. Muon studies of Au NPs encapsulated in 'SBA-15' silica are...

Hydrogen abstraction reactions are key steps in free radical mechanisms that dominate the combustion and atmospheric chemistry of the alkane hydrocarbons and, as such, merit...

The hyperhoneycomb lattice can be viewed as a 3D version of the 2D honeycomb and the new magnetic compound [(C2H5)3NH]2Cu2(C2O4)3 provides a rare example. Honeycomb type...

Graphite has been the first material ever studied by µSR, but a comprehensive scheme to understand its behaviour still lacks. In particular it is not properly known if and how...

With increasing demands for high performance/capacity rechargeable batteries the materials science community is currently facing two severe issues. First of all there is from a...

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 investigation of electron correlations in intermetallic alloys is fascinating. At times, depending on the nature and strength of correlations, the compounds exhibit...

Radio Frequency µSR provides a direct method for accurately determining muon hyperfine coupling constants, Aµ, for muoniated radical species. The method complements the well...

Hydrogen abstraction reactions are key steps in free radical mechanisms that dominate the combustion and atmospheric chemistry of the alkane hydrocarbons and, as such, merit...

Recently there has been an M(TCNQ)2, where M=Mn, Co, Fe and Ni, series synthesised where all samples formed a stochiometric glassy ferromagnetic salt. We have focused on the...

Hydrogen abstraction reactions are key steps in free radical mechanisms that dominate the combustion and atmospheric chemistry of the alkane hydrocarbons and, as such, merit...

We have developed a method to measure carrier recombination lifetime in crystalline silicon with the photo-muSR technique. The key of the method is to measure the dependence of...

Preliminary measurements of [FeFe]-hydrogenase model complexes were made in a previous experiment using EMU (RB 1010177). The results were interpreted in combination with DFT...

Many room temperature ionic liquids (salts with melting points near room temperature that hereafter will be referred to as ionic liquids) are ¿green solvents¿ for chemical...

Quantum spin liquids (QSL) are the materials, which does not show any magnetic ordering down to the absolute zero temperature. In our project we are trying to explore the fact...

The most important scientific problem to solve for our modern society is how to convert and store clean energy. We are currently on the verge for a general breakthrough in...

We propose a set of RF measurements on Silicon Carbide (polytype 6H) to identify and characterize the muonium species present below room temperature. One of the main goals of...

Small-sized metal nanoparticles (NPs) are of long standing interest to both magnetism and heterogeneous catalysis. Recent µSR studies of bare Au NPs encapsulated in mesoporous...
