High angular and spectral directional reflectance dataset of snow and sea-ice
This dataset includes the data published in Goyens et al. (2018, DOI:10.1002/2017EA000332). It provides the following parameters for the different ice, snow and ponded ice... -
Continuation of "Magnetic excitations in the quantum spin ice Yb2Ti2O7"
We have recently carried out an inelastic neutron scattering experiment at LET in order to investigate the excitations in the quantum spin ice Yb2Ti2O7. The single crystal... -
Are ice particles in the laboratory "good" analogues for collision studies of...
With the discovery of almost 3000 exo-planets it is clear that planet formation is a by-product of star formation, yet in the micron cm size range, where relative velocities... -
Phonon dispersions in the magnetoelastic spin liquid Tb2Ti2O7 and spin ice Ho...
We plan to measure the phonon dispersions of the rare earth pyrochlores Tb2Ti2O7 and Ho2Ti2O7 in their spin liquid and spin ice phases respectively. Magnetoelastic effects are... -
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... -
Kinetics of the ordering transition in ice Ih; crystal structure and thermal ...
Below 80 K ordinary water ice (ice Ih) undergoes a phase transition in which the randomly oriented molecules in the crystal adopt an ordered orientation. This ordered form of... -
Concerted proton tunnelling in ordinary ice
In a recent study we showed, by incoherent elastic and quasielastic neutron scattering measurements, the existence of non-harmonic motion of hydrogen in ordinary ice. The motion... -
Spin Dynamics in the isotopically enriched spin ice 162Dy2Ti2O7
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... -
Pair distribution function analysis of stacking disorder in ice
Very recently, the metastable cubic ice phase was renamed to stacking-disordered ice (ice Isd) in order to emphasise the fact that this form of ice contains not only cubic... -
Equations of state of D2O ice III and ice V
The high-pressure forms of ice, phases III and V, are the equilibrium solids in contact with liquid water at pressures between 2.5 - 5.5 kbar. Consequently, their properties are... -
Muon probes of hydrogen-bond network in supercooled water
Muon diamagnetic fraction in liquid water is known to decrease with decreasing temperature probably because its formation mechanism results from the structural alternation and... -
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... -
Structures and thermal expansivity of recovered phases of urea II & III
Urea is a prototypical hydrogen-bonded small molecule that has stimulated considerable fundamental research into its structure, elastic properties and polymorphism. Amongst the... -
Thermal expansion of recovered high-pressure ice polymorphs
The ambient-pressure phase of ice is a well-known example of a molecular solid that exhibits negative volume thermal expansion below 60 K. In a recent study carried out on HRPD... -
Spin dynamics in the quantum spin ice state of Yb2Ti2O7
We propose to carry out a muSR study of the spin dynamics in two single crystal samples of Yb2Ti2O7. Both samples are notionally stoichiometric but they have been prepared using... -

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... -
Ice β-XV – a novel ice polymorph
Water molecules can form different hydrogen-bonded networks, a property known as ice polymorphism. So far 18 different networks have been characterized using neutron diffraction... -
Unpicking the signal of partial order from thermal motion in diffuse scatteri...
Orientationally-disordered water molecules in ice adopt a degree of partial order upon cooling, a process that is halted by kinetics at ~100 K in pure ice and ~60 K in KOH-doped... -
