Abstract:
The conceptual designs of two nanoscale spin-Seebeck temperature sensors are proposed based on the longitudinal spin-Seebeck effect (LSSE) in bilayers made of a ferromagnetic insulator Y3Fe5O12 and a Pt, and the transverse spin-Seebeck effect in Ni81Fe19/Pt structure. The working principles of two sensors are presented. The direct conversion of the temperature information into the electric voltage is described in detail. Moreover, the effect of the spin Hall angle on the performance of sensors is discussed. The results obtained here reveal that the LSSE and TSSE have the potential to realize practical temperature sensors.
