摘要：

We report the successful fabrication of lateral organic spin valves (OSVs) using polycrystalline pentacene as spacer and half-metallic La0.7Sr0.3MnO3 (LSMO) as two electrodes. The distance between two electrodes ranges from 30 nm to 100 nm. The current-voltage characteristics follow the power law relation, which are attributed to the space charge limited current behavior. The devices with a spacing of 30 nm exhibits clear spin-valve characteristics with a magnetoresistance (MR) ratio of similar to 2% at 9K. The MR effects disappear for electrode spacing about 100 nm, suggesting that the spin diffusion length is less than 100 nm.
