Thermal transport measurements of spin ice materials

ORAL

Abstract

Extensive thermal conductivity measurements have been conducted on several rare-earth titanate materials. We report the consequences of crystalline quality and magnetic impurities on the mobility and dynamics of delocalized magnetic excitations. Detailed x-ray diffraction measurements have also been conducted on these samples to accurately characterize the sample quality. Differences between the various materials measured are also discussed.
