Spin-Caloritronics

Thermoelectric effects like the Seebeck and the related Peltier effect have been subject to extensive research for already more than fifty years. Renewed interest in this topic, driven by the progress in nanoscale spintronics, has led to a new research field called spin caloritronics. In this field the focus lies on how the spin degree of freedom may alter normal thermoelectric effects.

This research focusses on the experimental and theoretical work on thermal effects in non local spin valve devices at the nanoscale.
