Spin and Heat Transport in Nanoscale Superconductor Hybrid Structures

In nanoscale superconductors spin and heat currents are coupled in the presence of a spin-splitting field. This leads to large thermoelectric effects in a ferromagnet/superconductor tunnel junction, where the electron-hole symmetry is broken due to the spin polarization of the junction. This thesis presents the first experimental observations of thermoelectric current in such a junction.
