Fulleride superconductivity is experiencing a renaissance of interest following our recent discovery of superconductivity proximate to an antiferromagnetic Mott insulating state...

Extreme muon quantum effects will be studied in the simple organic molecule acetone using ALC spectroscopy to determine the quantum averaged hyperfine parameters of the state...

The kappa structural phase of BEDT-TTF salts incorporating various anions X provides an extremely interesting series of layered-structure strongly-correlated materials, whose...

The new molecular magnet bis(2,3-dimethylpyridinium) tetrabromocuprate (DIMPY) is a strong-leg spin ladder with a quantum critical point at 3 T separating a low-field...

We propose to study the dynamics of the central Fe spin in reduced model Fe-porphyrins. Our aim is to clarify a relatioship between the spin dynamics of Fe and functions of...

The great majority of known muonium defect centres and muonium substituted organic radicals have essentially spin-only magnetism, with few exhibiting any noticeable departure...

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...

SrCo2V2O8 is believed to belong to the same rare universality class as Tomonaga-Luttinger liquids, which may be descrived by the 1D XXZ model. In SrCo2V2O8, this is accomplished...

Molecular nanomagnets (MNMs) comprise clusters of exchange coupled transition metal ions which often have a negative anisotropy constant, favouring a ground state with a large...

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...

Ca3CoMnO6 has alternating ions in ferromagnetic Ising chains that are antiferromagnetically coupled on a triangular lattice and realizes an important model in frustrated...

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...

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 magnetic ground state of a compound containing higher d-orbital (4d/5d) is fascinating due to its various competing effects like extended orbital, pronounced crystal field...

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 =...

In this proposal, we wish to study the origin of the multiferroic nature in Sr4Fe2(CO3)O6. In the magnetization data, antiferromagnetic (AFM) ordering appears at TN = 340 K and...

The new molecular magnet bis(2,3-dimethylpyridinium) tetrabromocuprate (DIMPY) is a strong-leg spin ladder with a quantum critical point at 3.0(3) T separating a low-field...

Spin ladders present a class of low-dimensional quantum magnets that occupy a regime of rather subtle behavior which lies between the stark extremes of a one-dimensional chain...

Investigation of spin fluctuation dynamics interactions in Heusler alloys is interesting. Depending on the nature and strength of correlations, these compounds exhibit...

The main spectroscopic technique for studying radicals in solids and liquids, ESR, cannot usually be used to study radicals of more than 3-5 atoms in the gas phase due to strong...
