β-Tantalum, a better candidate for spin-to-charge conversion

Abstract: Development of thermoelectric energy harvesting devices has hit a stumbling block due to the intrinsically linked electrical and thermal conductivities of materials. However, this field can still be improved by employing devices that take advantage of spin-based effects. A temperature gradient can be converted to a spin-polarized current in a ferrimagnetic insulator by the spin Seebeck effect (SSE), and that spin current can be converted to an electrical voltage in a heavy metal by the Inverse spin Hall effect… Show more

“…The coercivity values in both directions for the YIG(5 nm)/Pt and YIG(3 nm)/Pt samples are characterized by the longitudinal spin Seebeck effect induced inverse spin Hall effect voltage (V ISHE ). [28][29][30] As shown in Figs. 1(a) and 1(b), both samples have small coercivities.…”

“…This effect has been observed in a large range of systems, including ferrimagnets, [1][2][3] antiferromagnetic, [4] and even some paramagnetic materials. [5] Using a metal with strong spin-orbit coupling, [1,[6][7][8] the thermally pumped spin current could be converted to charge current by the inverse spin Hall effect (ISHE). Recently, the conversion of the spin current generated by LSSE to the charge current was also observed in the topological insulator due to the inverse Rashba-Edelstein effect.…”
