研究了含间隔层的共轭聚合物区域规则聚（3-己基噻吩）（RR-P3HT）有机自旋阀在室温下的磁电阻。研究了有机间隔层厚度对Fe50Co50 / rr / p3ht / Ni81Fe19自旋阀磁阻的影响。结果表明，磁流变率随层厚的增加而减小，这与材料的自旋相干长度一致。在室温下观察到磁电极中存在两种磁阻效应，即自旋阀磁阻和各向异性磁阻。
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.
