Thermoelectric-induced spin currents in single-molecule magnet tunnel junctions

摘要

A molecular spin-current generator is proposed, which consists of a single-molecule magnet u0002SMMu0003ncoupled to two normal metal electrodes with temperature gradient. It is shown that this tunnelingnjunction can generate a highly spin-polarized current by thermoelectric effects, whose flowingndirection and spin polarization can be changed by adjusting the gate voltage applied to the SMM.nThis device can be realized with current technologies and may have practical use in spintronics andnquantum information. © 2010 American Institute of Physics. u0004doi:10.1063/1.3525571
