中文摘要	The magnetic/organic/magnetic spin valve structure has been fabricated with pi-conjugated molecular pyrrole derivative 3-hexadecyl pyrrole as the spacer layer by Langmuir-Blodgett (LB) technique. It shows giant magnetoresistance (MR) as large as 20% at room temperature, demonstrating that low-energy electrons can traverse the molecular barrier while remaining spin polarized. The spin transport across organic structures is diffusive from its current-voltage (I-V) curve under bias voltage up to 1V. The MR value decreased when the LB-film layer increased. The telegraph noise and the layer dependent MR value suggest that the spin-polarized transport signals can be degraded by localized states in the molecular barriers and barrier quality.
