This proposal is to observe single-spin diffusive motion on a two-dimensional (2D) percolating network having a fractal geometry. The random walker¿s travel times on a...

Ammonia borane (AB) is one of the most promising hydrogen storage materials. We have extensively studied the low temperature behaviour of this material This proposal asks for 3...

Pure Ca3Co2O6 is a model system of ferromagnetic Ising chains arranged antiferromagnetically on a triangular net. Furthermore this system has aroused great interest because at...

The proposal addreses the compounds PrPtAl and YbNiSn. Both systems are canted ferromagnets with both materials undergoing moment reorientation transitions as a function of...

The use of the J 0-to-1 rotational transition of dihydrogen has been extensively used to characterise the state if hydrogen in and on materials. The disadvantage of studying the...

The defect thiospinel, GeV4S8 adopts a cubic structure at room temperature (space group F-43m). We have identified a new monoclinic phase of this material at 2K, which may be...

Magnetically frustrated materials are unable to adopt the regular long-range ordered states observed in conventional insulating transition metal oxides. Instead they tend to...

Antiferromagnetic interactions on geometrically frustrated lattices such as the fcc lattice can result in novel magnetic states and structures. Ba2CoMoO6 is an fcc...

KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling...

We will study H2 dynamics in the nanotubular clay imogolite whose structure has an external diameter of ~2.5 nm and an inner diameter of <1 nm. The tube length of synthetic...

The aim of this proposal is to study the field induced magnetically ordered phase of the quasi 1D spin system copper nitrate. We plan to study the integrated intensities of the...

Yttrium iron garnet Fe3Y5O12 (YIG) is the material of choice for spin Hall related effects, magnonics, inter alia and has been used in microwave applications for many years....

Quantum spin liquids (QSLs) are intriguing states of matter in which magnetic frustration and strong quantum fluctuations prevent classical long-range magnetic order. To date,...

Recently we have investigated magnetic and quadrupolar ordered states of YbRu2Ge2 using zero-field muon spin relaxation (µSR), neutron diffraction and inelastic neutron...

Layered perovskites are well known functional materials but, in the context of fluoride chemistry, have so far been restricted to purely inorganic examples: K2NiF4 is the...

In this proposal we aim to study the low temperature uptake and dynamics of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual...

Dense corrdination frameworks that contain inorganic centres connected into extended lattices by polyatomic anions often adopt highly anisotropic structures. Thus they often...

Al2SiO5 forms three naturally-occurring polymorphs, kyanite, andalusite and sillimanite. These minerals are produced by varying degrees of metamorphism of sedimentary rocks, the...

High sorption capacities and enhanced interaction strengths are the two most fundamental prerequisites for the deployment of carbon-based materials as hydrogen-storage media. In...

Two days of beamtime on HRPD will be used to examine a family of double perovskites Sr2YbMO6 that are isostructural at room temperature. When M = Mo5+ the monoclinic perovskite...
