The properties of pnictide superconductors can be controlled exquisitely by chemical doping. We have identified some key systems in which to explore this effect which should...

The crystal structure of R2T(Ni,Co)Si3 consists of hexagonal layers of rare-earth atoms and randomly distributed T-Si arranged alternately along hexagonal c-axis. Magnetic...

The structure and dynamics of hydrogen (H) defects in tungsten recently become a topic of major interest since this metal has been chosen as shielding material for the next step...

In the field of semiconductor spintronics, n-type GaAs has been utilized as a prototype system, where one can inject electronic spin and study its behavior with optical...

We have discovered an unusual magnetovolume effect in the 6H-perovskite oxides Ba3BiIr2O9 and Ba3BiRu2O9. These compounds contain isolated face-sharing bi-octahedral dimers...

By means of a positive muon spin rotation and relaxation (mu+SR) technique, we have investigate Li and Na ion diffusion in many battery materials. Among them, it was found that...

Gaining control of the building blocks of magnetic materials will enable the design and growth of bespoke magnetic devices. However, the ability to tune the magnetic...

Mimicking the motion of functional biological systems has become possible as a result of sophisticated modern nanotechnology and materials science.In the layered organic quantum...

Previous muon experiments have identified a muonium state in the commonly occuring, but complex, beta rhombohedral form of elemental boron. To complement recent theoretical work...

The mechanism of action of inhalation anaesthetics such as N2O and the inert gases are unclear. Direct binding to receptor sites on membranes would rely on weak intermolecular...

Using the Emu spectrometer at ISIS we have recently studied charge carrier transport in the technologically important molecule 8-hydroxy-quinoline aluminium, by probing the...

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...

Discrete energy level form in quantum mechanical systems and if carefully measured the population density of the levels can be probed and manipulated. The consequence of this...

We propose to use muon spin relaxation to examine the anomalous magnetic phase behaviour of Ba2MnMoO6. This compound shares the frustrated geometry that leads to a valence bond...

At low temperatures and high magnetic fields, the electron in a muonium or radical state may be polarised if it has an opportunity to reach thermal equilibrium. Such a...

The heat capacity and neutron powder diffraction measurements of the double perovskites La2NaB′O6 (B = Ru5+, Os5+) with S=3/2 on the B¿ reveal an incommensurate magnetic...

The recovery of the muon polarization in a longitudinal magnetic field has been used to obtain the muon hfcs of organic radicals. In pure benzene there is a single step in the...

The iron-based superconductor LiFeAs exhibits a number of unique features distinguishing it from other materials in its class. As yet, these differences are unexplained. This...

There is a large emphisis on fucntialising materials to create magnetic and electrical materials. Tetracyanoquinodimethane is a famous material discovered in the 1960 and ws...

A randomly diluted ferromagnet has its transition temperature Tc suppressed to a quantum critical point. Between the Tc of the diluted material and that of the undiluted...
