“…Pure spin currents, 7 resulting from the spin up and spin down electrons flowing to the left and right electrodes, respectively, are one of the research hotspots in the field of spintronics, because they reduce the interaction between the electrons and thus decrease the Joule heat. 8 So far, many methods have been developed to generate pure spin currents, for example, spin hall effects, 9 adiabatic quantum pumps, 10 optical injection, 11 spin-dependent Seebeck effects, 12,13 and a threeterminal model. 14 However, there are only two main methods to realize pure spin current in two-dimensional (2D) materials, which are the photogalvanic effect (PGE) and spin-Seebeck effect (SSE).…”

Spin caloritronics is a newly-explored research field concerning mainly the interaction of spin and heat, and has attracted extensive research interests recently. Heat generation in magnetic multilayers is a serious problem, because it has significant effects on the electric, thermal, and magnetic properties of nanoscale electronic devices. Here we study theoretically the heat generation due to spin transport in magnetic multilayers by using a macroscopic approach based on the Boltzmann equation. There exists extra heat generation due to spin accumulation besides the nominal Joule heat, when a current flows through the magnetic multilayers. On the basis of the giant magnetoresistance (GMR) model, we derived the expressions for the distribution of heat generation. We also compared the distribution and magnitude of the heat generation in antiparallel (AP) and parallel (P) alignments. Our analysis shows that the AP alignment leads to larger heat generation than the P alignment. Therefore, the heat generation in the structure changes dramatically with the relative alignment of the two ferromagnetic layers, which is similar to the GMR effect.
