The purpose is to follow a structural evolution as water soluble (normal curvature) micelles are gradually transformed into oil soluble (reversed curvature) aggregates. Although...

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...

The (NH4)0.02 Rbx K0.98-x I system offers advantages for the systematic study of tunnelling species and how they interact. Currently there are two models to explain the dynamics...

Single crystal, bulk Si1-xGex alloys are available across the alloy composition range, and provide opportunity for study of alloy properties in transition between the two...

The current experiment proposes to identify and study the spin dynamics of the muon states formed in octabutoxy-phthalocyanine (oBu-H2Pc) using the avoided level crossing...

Crystals of the filled skutterudite PrFe4Sb12 with the 73~87% Pr-site filling fractions prepared under ambient pressure show some magnetic ordering around 5 K and their...

We propose measurements of the elementary phonon-roton (p-r) excitations of liquid 4He confined in porous MCM-41 (45 Å pore diameter) at wave vectors Q ¿ beyond the roton¿, 2.4...

Liquid light and heavy water are the most widely used moderator and reflector materials in nuclear reactors, however there is a lack of knowledge of the vibrational density of...

The objective of this experiment is the study and characterization of spin-polarized electron states at the interface of EuO and 3d transition metal oxides. EuO is a...

We request four days of beam time to conduct zero and longitudinal field measurements on iridate pyrochlores A2Ir2O7 (A = Y, Lu, Nd) in the temperature range 200 K to 2 K and in...

In this proposal we want to address the issue of the identification of the different muonium adducts that are possible in Alq3 without any crystallographic constraints, and...

The object of this proposal is to measure the partial vibrational density of states (VDOS) within the incoherent approximation for the archetypal 'strong' network forming glass...

While we now have a complete picture of the average local and intermediate structures of the various amorphous ices, their dynamic behaviour (glass transition and defect...

Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and...

Ho2-xYxSn2O7 is characterized by degenerate magnetic ground-states, which involve the magnetic structure for x->0 (Spin-Ice phase) and the two-fold degeneracy of the...

The method of Se isotope substitution with inelastic neutron scattering will be used to measure the partial VDOS for As2Se3 glass. This is a prototypical network forming...

In recent incoherent inelastic neutron scattering experiments we have shown that the anharmonic single-particle dynamics of H2 can be measured with high precision in quantum...

Following recent experiments in which the shallow donor muon states in semiconductors are found to have significant electron polarisation at low temperatures and high fields, we...
