Abstract We report the spin transport properties in a pigment-red (perylene-3,4,9,10-tetracarboxylic dianhydride: PTCDA) film prepared by thermal evaporation. In a palladium (Pd)/PTCDA/Ni80Fe20 tri-layer sample, a pure spin-current is generated in the PTCDA layer by using the spin-pumping driven by the ferromagnetic resonance of the Ni80Fe20 film. The generated 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 spin transport in a PTCDA film, and it is confirmed that a PTCDA film is useful not only as a robust protection layer material but also as a spintronic material.

热蒸发色素红膜中自旋泵诱导的自旋输运

摘要 我们报告了通过热蒸发制备的颜料红（苝-3,4,9,10-四羧酸二酐：PTCDA）薄膜的自旋输运特性。在钯 (Pd)/PTCDA/Ni80Fe20 三层样品中，通过使用由 Ni80Fe20 膜的铁磁共振驱动的自旋泵浦，在 PTCDA 层中产生纯自旋电流。产生的自旋电流被 Pd 层吸收，通过 Pd 中的反自旋霍尔效应转换为充电电流，并作为电动势检测。这是 PTCDA 膜中自旋输运的明确证据，并且证实 PTCDA 膜不仅可用作坚固的保护层材料，还可用作自旋电子材料。
