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... -
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...
