本文报道了热蒸发法制备的五苯薄膜的自旋泵诱导的自旋输运性质。在钯(Pd)/并五苯/Ni80Fe20三层样品中，Ni80Fe20的自旋泵送在并五苯层中产生了纯自旋电流，该自旋电流与自旋注入中的电导失配问题无关。自旋电流被吸收到Pd层中，在Pd中转化为具有逆自旋霍尔效应的电荷电流，并被检测为电动势。这为热蒸发制备的五苯薄膜在室温下存在纯自旋电流提供了明确的证据。
We report the spin-pump-induced spin transport properties of a pentacene film prepared by thermal evaporation. In a palladium(Pd)/pentacene/Ni80Fe20 tri-layer sample, a pure spin-current is generated in the pentacene layer by the spin-pumping of Ni80Fe20, which is independent of the conductance mismatch problem in spin injection. The spin current is absorbed into the Pd layer, converted into a charge current with the inverse spin-Hall effect in Pd, and detected as an electromotive force. This is clear evidence for the pure spin current at room temperature in pentacene films prepared by thermal evaporation.
