Spin-dependent thermoelectric effects in superconductor-ferromagnet tunnel junctions — Stefan Kolenda1, Christoph Sürgers2, and •Detlef Beckmann1 — 1Institut für Nanotechnologie, Karlsruher Institut für Technologie — 2Physikalisches Institut, Karlsruher Institut für Technologie
Recently, large thermoelectric effects were predicted to occur in superconductor-ferromagnet tunnel junctions with a spin-splitting of the density of states [1]. We have reported on the observation of these effects in samples where the spin splitting was induced by an applied magnetic field [2]. Here, we show results on samples where the spin splitting is enhanced by exchange coupling to the ferromagnetic insulator europium sulfide.
