Thermoelectric effects in superconductor-ferromagnetic hybrids

ORAL

Abstract

The conflicting spin order in superconductor-ferromagnetic systems has lead to a host of facinating phenomena. However, most experimental studies have focused on electrical and spin transport measurements. While there have been numerous theortical predictions of exciting thermal phenomena, thermal properties of these systems remains largley unexplored. In particular, thermoelectric effects which are usually negligible in superconductors have been predicted to increase dramatically in superconductor hybrid structures when in the presence of a spin splitting exchange field. This presentation will focus of the experimental design and measurement of the Seebeck coeffient in superconductor-ferromagnetic hybrids.
