Eschrig, Matthias Machon, Peter Physical Review Letters : PRL ; 110 (2013), 4. - 047002 Nonlocal Thermoelectric Effects and Nonlocal Onsager relations in a Three-Terminal Proximity-Coupled Superconductor-Ferromagnet Device eng Eschrig, Matthias 2013 Machon, Peter Belzig, Wolfgang 2013-03-18T10:53:52Z 2013-03-18T10:53:52Z We study thermal and charge transport in a three-terminal setup consisting of one superconducting and two ferromagnetic contacts. We predict that the simultaneous presence of spin filtering and of spindependent scattering phase shifts at each of the two interfaces will lead to very large nonlocal thermoelectric<br />effects both in clean and in disordered systems. The symmetries of thermal and electric transport coefficients are related to fundamental thermodynamic principles by the Onsager reciprocity. Our results show that a nonlocal version of the Onsager relations for thermoelectric currents holds in a three-terminal quantum coherent ferromagnet-superconductor heterostructure including a spin-dependent crossed Andreev reflection and coherent electron transfer processes.
