Spectroscopy of Spin Fluctuations in Spin Ices

ORAL

Abstract

In the past decade, the theoretical prediction of emergent magnetic charges in several lanthanide-pyrochlore magnetic insulators1 has spawned renewed experimental interest in the study of these elusive particles, albeit in a condensed matter system. Thermodynamic and transport studies of of the spin ice of Dy2Ti2O7 and Ho2Ti2O7 are the focus of research. We report new studies of the spin fluctuation spectrum in these materials and analyze the data in the context of theories for thermally generated magnetic monopole pairs.
