In recent work Moessner and colleagues have demonstrated that thermally induced defects in spin ice behave as emergent magnetic monopoles. Within the material there exist...

To the best of our knowledge, there is no previous work on using muons to measure photo-excited states in organic semiconductors or related materials. Our photo-excitation ideas...

During our previous experiment on HiFi (RB1320541) we measured the ALC spectrum of the Fe2(µ-pdt)(CO)4(PMe3)2 model hydrogenase complex over multiple temperatures. The spectra...

We propose a study of the magnetic structure of isotopically enriched Gd2Ti2O7. We have successfully grown and characterised large single crystals using low-absorption 160Gd. In...

Mixtures of methanol with water and ammonia dominate the chemistry of cometary bodies, leftovers of the building blocks of the outer planets. We have previously determined the...

Ho2Ir2O7 has a cubic pyrochlore structure. Trigonal crystal fields at both the Ho and Ir sites create Ising-like moments that can order in a non-collinear arrangement with...

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...

It has very recently been shown that Mott-insulators located at the crossover regime closer to the itinerant side, such as RNiO3, undergo a pressure-induced transition into a...

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...

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...

CePd3 is a classic intermediate valence (IV) system. In MAPS experiment 620167 we obtained an important qualitative result for CePd3, namely that the Kondo-like scattering...

Inter-layer exchange coupling through charge and/or spin carriers is the key control mechanism for the field of nano-magnetism and is often coupled to other spintronic effects,...

We have begun an experimental program to investigate the denaturing of DNA, using scattering techniques, to test statistical mechanical models for the moelcule. It is believed...

Today, about seventy years after Laves, there exists a fairly good knowledge about the basic structural principles of Laves phases but many questions still remain. AMn-type...

Exchange interactions in insulators can be understood in terms of the Andersen exchange picture in which the Hamiltonian has two contributions: (i) a kinetic term characterized...

We propose to investigate the high-energy (above 10 meV) excitations using either the MERLIN or MAPS chopper instruments. CaFe2O4 is interesting for several reasons. First, it...

This proposal is part of our research programme on spin and orbital order in frustrated systems. AgNiO2 has a layered crystal structure with Jahn-Teller active Ni3+ ions forming...

Recently we have carried out inelastic neutron scattering measurements on Li2RuO3 to understand the nature of the phase transition at 550K. We have seen a clear inelastic...
