Magnetic Charge Transport in Spin Ice
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... -
Magnetic correlations in yttrium diluted Ho2-xYxTi2O7 spin ice.
Pure Ho2Ti2O7 exhibits spin ice beahviour. Studies of doped spin ice, replacing Ho with non-magnetic Y, suggest that the spin ice state is present even when the amount of doping... -
A Study of AuMu^+ Final States by Dia RF Resonance
Small-sized metal nanoparticles (NPs) are of long standing interest to both magnetism and heterogeneous catalysis. Muon studies of Au NPs encapsulated in 'SBA-15' silica are... -
Hydrogen impurity in solar cell materials CIGS and CZTS
In this proposal we intend to complete the characterization of the hydrogen impurity in solar cell materials Cu2ZnSnS4 (CZTS) and Cu(In,Ga)Se2 (CIGS), by using the positive... -
Spin dynamics of Ce in the Noncentrosymmetric Heavy-Fermion Superconductors C...
In centrosymmetric heavy-fermion (HF) superconductors Cooper pairs have either singlet or triplet symmetry. Recently a handful of non-centrosymmetric Ce-based HF compounds have... -
Spin dynamics and magnetic ordering in the p-orbital molecular solids CsO2 an...
A magnetic response of the alkali-metal superoxides comes from the p-orbital S = 1/2 spins of anionic O2- molecules. As the O2- molecules are highly reorientable and the... -
Kinetics of Hydrogen Abstraction in Alkanes by Mu Reactivity studied by RF Re...
Hydrogen abstraction reactions are key steps in free radical mechanisms that dominate the combustion and atmospheric chemistry of the alkane hydrocarbons and, as such, merit... -

Muonium in BeO
BeO is a promising material in order to improve HfO2-based MOSFET devices, and a candidate substitute of HfO2 as high-k gate material. The electrical properties of BeO can be... -
Magnetic properties of yttrium diluted Ho2-xYxTi2O7 spin ice.
Pure Ho2Ti2O7 and Dy2Ti2O7 exhibit spin ice behaviour. The recent discovery of monopoles and "magnetricity" in Dy2Ti2O7 spin ice has only added to the interest in these... -
RF-muSR in the gas phase: the muoniated ethyl radical
Radio-frequency muon spin resonance is an exceptional technique for studying free radicals, but it has not been applied to study radicals in the gas phase. In a previous... -
Search for monopoles in spin ice via the exterior field distribution
Bramwell et al. have provided an elegant demonstration of dynamics in magnetic monopoles in spin ice measured by muons implanted inside the sample. However, it is likely that... -
Magnetic Charge Transport in Spin Ice
The transport of electrically charged quasiparticles plays a pivotal role in modern technology. In contrast, the transport of magnetic charges has barely been explored... -
Tuning the low-temperature magnetism of spin ice Dy2Ti2O7: Y-substitution and...
The spin ice compounds Dy2Ti2O7 and Ho2Ti2O7 have come to enormous attention in the past year with the observation of excitations resembling magnetic monopoles. Here we propose... -
The search for magnetic monopoles in spin ice.
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... -
Investigation of the magnetic phases of the charge transfer compound CuTCNQ
The charge transfer compound CuTCNQ (TCNQ = 7,7,8,8-Tetracyanoquinodimethane) exhibits switching between two electrical resistance states when subject to an electric field. It...
