Description
In classical spin ice emergent magnetic monopole excitations have been predicted, and in quantum spin ice a Higgs transition is expected from a magnetic Coulomb liquid to a ferromagnetic phase. In this talk I shall explore how diffuse neutron scattering has been used to determine defect structures, the magnetic ground states and the monopole dynamics in pyrochlores. Polarised neutrons are used to separate the structural and magnetic contributions. Diffuse neutron scattering is severely signal limited and, therefore, this is an area where the ESS could potentially make an important contribution.
