We have performed further measurements on Dy2Ti2O7 and confirmed the observation of magnetic charge transport. Given the time constraints of our previous experiment not all...

The frustrated pyrochlore Er2Ti2O7 is a rare example of a magnetic system in which quantum fluctuations are capable of selecting a unique ground state out of the macroscopically...

We plan to study the non-thermal microwave (MW) effects on H2O2 through its reaction with muonium under MW irradiation. The key objectives are 1) for the first time definitively...

This study involves attempting to understand the Li atom diffusion within Li-intercalated hexagonal boron nitride. Muons present a significant advantage as they are sensitive to...

The quaternary boronitride superconductor La3Ni2B2N3-d (Tc~12-14 K) has a layered structure where LaN-LaN-LaN triple layer blocks alternate with NiB layers. These NiB sheets are...

In recent years, nanoparticles have been a major source of interest in a wide range of fields. Our long term objectives are tuning the free radical reactivity on the surface of...

Amorphous molecular magnetic materials Ni2(OA) (OA:organic acceptor) were reported to exhibit ferromagnetism with Curie temperatures >400K. This work is controversial as it...

We aim to continue our investigation of the high temperature magnetic interactions in LaCoO3. Our previous experiment has confirmed magnetic susceptibility data, with a change...

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...

Topological insulators are 3D materials with a band gap in the bulk-electronic structure but with gapless, delocalized, surface states. The most studied topological insulator is...

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...

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...

Sr3Ru2O7 is an unusual layered oxide metamagnetic metal. It has been know for some time that the application of a large magnetic field (~8 T) perpendicular to the RuO2 planes...

For one-dimensional quantum spin chain systems recent experimental and theoretical studiesindicate unexpectedly large, in some cases diverging spin and heat transport...

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

CeRhIn5 is an antiferromagnetic itinerant magnet which illustrates a temperature and pressure interplay between antiferromagnetism and superconductivity. Recently, it has been...

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...

Our susceptibility studies of the frustrated magnet Yb2Sn2O7 has revealed a spin glass transition of the Yb3+ magnetic lattice at T_g = 140 mK. To our knowledge, this...

We have recently performed a ZF muon experiment on Ba3Dy2GaNb9O30 in EMU under the influence of electric fields and demonstrated that this material demonstrates multiferroic...

Spin ice materials exhibit novel magnetic behaviour because of their atomic interactions and geometric constraints of the crystal lattice. This novel behaviour takes the form of...
