" The 토토 사이트 degree of freedom of the electron affects not only charge, but also heat and thermoelectric transport, leading to new effects in small structures that are studied in the field of 토토 사이트 caloritronics (from calor, the Latin word for heat).
This lecture addresses the basic physics of 토토 사이트 caloritronics. Starting with an introduction into thermoelectrics and Onsager’s reciprocity relations, the generalization to include the 토토 사이트 dependence in the presence of metallic ferromagnets will be addressed. Using this foundation I will describe several recently discovered 토토 사이트-dependent effects in metallic nanostructures and tunneling junctions as well as a zoo of 토토 사이트-related thermal Hall effects in terms of a two 토토 사이트-current model of non-interacting electrons (an overview of the recent literature is given in Ref. 1).
Next, I will argue that different classes of 토토 사이트 caloritronic effects exists that can be explained only by the collective 토토 사이트 dynamics in ferromagnets. The thermal 토토 사이트 transfer torque that allows excitation and switching of the magnetization in 토토 사이트 valves as well as the operation of nanoscale heat engines is complemented by thermal 토토 사이트 pumping. The latter generates the so-called 토토 사이트 Seebeck effect, which is generated by a heat current-induced non-equilibrium of magnons at a contact between an insulating or conducting ferromagnet and a normal metal. Under these conditions a net 토토 사이트 current is injected or extracted from the normal metal that can be detected by the inverse 토토 사이트 Hall effect.
Both classes can be formulated by scattering theory of transport in the adiabatic approximation for the magnetization dynamics and computed in terms of material-dependent electronic structures. Further issues to be addressed are the relation between electric, thermal and acoustic actuation, as well as the application potential of 토토 사이트 caloritronics.
