Abstract
The authors investigate the effect of Rashba spin-orbit interaction (SOI) and external magnetic field on the thermospin properties of a quasi-one-dimensional ballistic electron system. Spin analogs to the thermoelectric Seebeck coefficient and figure of merit (FOM) are defined and studied. Sign reversal and oscillation of spin Seebeck coefficient are indicated as a function of junction parameters. With the increase of SOI strength, the spin Seebeck coefficient oscillates more rapidly and the intervals between adjacent peaks are narrowed. Because large thermal conductance is induced by the more conducting paths, spin-FOM in the presence system is smaller than that of a quantum dot device.
