Thermomagnetic properties of single-crystal Holmium

ORAL

Abstract

This talk will present results of experiments intended to experimentally map out the complete thermomagnetic transport tensor of elemental holmium. An emphasis has been placed on examining the evolution of these properties as the material crosses between its various magnetic phases, including the unusual helical anti-ferromagnetic state. This state is particularly interesting due to the gradual rotation of the local magnetic moments that leads to their net global cancellation, as the impact of this type of ordering on the thermomagnetic transport properties has yet to be fully explored. Specifically, we will report results of the magneto-thermopower, magneto-thermal conductivity, and the Nernst coefficient on single crystal samples.
