The magnetoresistance (MR) of organic spin valves containing the spacer layer regioregular poly(3-hexylthiophene) (RR-P3HT), which is a conjugated polymer, has been studied at room temperature. Investigations have been made of the influence of the thickness of organic spacer layer on the magnetoresistance of Fe50Co50∕RR-P3HT∕Ni81Fe19 spin valves. It was determined that the MR decreased as the layer thickness increased, consistent with the spin coherence length in this material. It has been observed at room temperature that there is the co-occurrence of two magnetoresistance effects, the spin-valve magnetoresistance, and anisotropic magnetoresistance in the magnetic electrodes.
