The fabrication and the measurements of the transport properties of magnetic tunnel junctions containing octanethiol tunnel barriers was discussed. It was found that the spin polarized tunneling could be observed in transport through these molecular devices. The devices exhibited changes in resistance as the angle between the magnetic moments in the two electrodes was varied showing that low energy electrons could traverse the molecular barrier while remaining spin polarized. The results show that the spin polarized transport signals could be degraded by localized states in the molecular barriers.
