muSR investigation of spin liquid Tb2Ti2O7
Among the rare earth titanates and stannates cristallising in the pyrochlore crystal structure, Tb2Ti2O7 is a singular system since its ground state is believed to be a spin... -
Do defect structures in the pyrochlore Tb2Ti2O7 control hidden order or the t...
The rare earth pyrochlores have been at the forefront of research into exotic magnetic phenomena for some years. In general they are of interest because they are frustrated -... -
Determining Microscopic Origins of the Thermal Hall Effect in Tb2Ti2O7
Studies of thermal Hall effects in insulating materials ascribe its microscopic origins to charge-neutral bosonic carriers generated by non-zero Berry curvature in the... -
Does the muon reach thermal equilibrium in a frustrated magnet?
The usual assumption that the muon's polarisation relaxes to zero at long times may be incorrect at high B and low T: for 5T and 30mK the Brillouin function gives P=49%. We plan... -
High Field muSR of Dy2Ti2O7 along [111]: Investigating a partial magnetizatio...
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... -
Varying oxygen content in the quantum spin ice Tb2Ti2O7
Tb2Ti2O7 is one of two compounds identified as potential quantum spin ices. As with other oxide pyrochlores the properties depend sensitively on the oxygen stoichiometry. Most... -
Magnon decay below the critical field in the S=1/2 Heisenberg antiferromagnet...
The two dimensional Heisenberg antiferromagnet on a square lattice is one of the most studied model quantum magnets. This is in part due to its intrinsic interest but also to... -
Hunting for the low-temperature, low-field magnetization plateau in Tb2Ti2O7
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... -
Magnetic structure of pyrochlore irridate Y2Ir2O7
We propose to study by powder neutron diffraction the ordered magnetic state of the pyrochlore compound Y2Ir2O7. There is currently an increasing interest in the condensed... -
Structural characterisation of new Li- and Na-ion conductors for potential us...
Re-chargeable Li ion batteries play a key role in modern consumer electronics and may have an important part to play as energy storage devices in a low carbon economy of the... -
Determining Microscopic Origins of the Thermal Hall Effect in Tb2Ti2O7
Studies of thermal Hall effects in insulating materials ascribe its microscopic origins to charge-neutral bosonic carriers generated by non-zero Berry curvature in the... -
Dynamical Signatures of Quantum Spin Ice in Tb2Ti2O7
We propose the first neutron scattering experiment on the frustrated magnet Tb2Ti2O7 in the presence of a magnetic field along [111]. This will allow us to uncover signatures of... -
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...
