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...

In an attempt to study the dynamics of Dy2Ti2O7 measured using muons we have made a sample of 162Dy2Ti2O7 where the 161 and 164 isotopes are reduced to a minimum (max. 0.6% of...

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 electronic properties of the second and third row transition metal oxides are traditionally thought to be dominated by the width of the 4d or 5d valence band, which reduces...

The transport of electrically charged quasiparticles plays a pivotal role in modern technology. In contrast, the transport of magnetic charges has barely been explored...

This proposal describes a muSR experiment on a garnet-type Li ionic conductor, Li6.75La3Zr1.75Nb0.25O12 under electric field (E) in order to study a diffusive behavior under a...

In this experiment we will use the F-mu+-F state as a window into the dynamics of perfluoroalkanes and polytetrafluoroethylene (PTFE) at the molecular level. We will investigate...

In a recent letter to Nature, Boothroyd and coworkers have shown that the well known hour-glass spectrum, previously observed in some cuprate materials, occurs in a hole doped...

Recent investigations into spin ice suggest excitations that behave like magnetic monopoles, this has included a transverse field muon experiment. When zero field muon...

Here we propose to investigate the fluroide containing compounds - AgF2, CuF2 and Cs2CuF4. By taking advantage of the F-mu-F coupling wich occurs in these compounds, we will...

Tb2Ti2O7 is a pyrochlore antiferromagnet that has previously been viewed as a spin liquid. This description fails to describe key features of its physics and more recently the...

We have observed an anomalous monotonically increasing longitudinal field relaxation rate in LiY_(1-x)Ho_xF_4 for applied fields above 1000 G (along the c-axis) and at a...

In recent years there has been a large interest in geometrically frustrated magnetic systems, especially those with spins interacting on two-dimensional triangular lattices...

Topological insulators (TIs) are of inherent interest as they are conducting on the surface whilst insulating on the bulk. We would like to investigate magnetically doped...

We request four days of beam time to conduct zero, transverse, and longitudinal field measurements on pyrochlore iridates A2Ir2O7 (A-227) with A = Yb, Y, Nd in the temperature...

Dy2Ti2O7 is a pyrochlore antiferromagnet that has a partial magnetization plateau between 0.1 and 0.9T for magnetic fields applied along the [111] direction. This represents a...

The origin of the Invar effect, whereby certain ferromagnetic alloys exhibit near zero thermal expansion around room temperature is still not properly understood. Although the...

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...

Multiferroic materials which exhibit both ferroelectric and (anti)ferromagnetic ordering are of great technological importance offering the potential for the design of novel...

Recent work has revealed that metal-organic frameworks (MOFs) can also exhibit this multiferroicity. These materials are particularly interesting since their structures are...
