Crystal Field Excitations in the Borderline Spin Ice Pr2Zr2O7
The title compound is expected to be a spin ice close to an instability which stabilises magnetic order. We can determine its spin Hamiltonian precisely by measuring the crystal... -
Tunable algebraic correlations and Kasteleyn transition in kagome ice
We propose to continue our search for the Kasteleyn transition in the kagome ice phase of the spin ice Ho2Ti2O7. The experiment requires the applied magnetic field to be... -
Quasielastic scattering in stuffed spin ices: defects or low lying singlets?
The subjects of this proposal, Ho2+xTi2-xO7-x/2, are brand new materials1 related to Ho2Ti2O7, a spin ice2,3. They have the remarkable property of remaining disordered at very... -
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... -
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... -
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...
