本研究使用有機高分子半導體製程技術取代小分子半導體製程技術以節省薄膜製程所需花費的時間，實驗使用之有機高分子半導體材料為聚(3-己基噻吩) (Poly(3-hexylthiophene-2,5-diyl), P3HT)並藉由摻雜超順磁性的Fe3O4磁性奈米粒子，來了解有機磁性高分子半導體的磁特性表現，實驗結果顯示，有機磁性高分子半導體薄膜較純的Fe3O4磁性薄膜具有較高的矯頑力，說明有機高分子半導體P3HT與Fe3O4磁性奈米粒子之間有產生自旋耦合(Spin-Coupling)之量子效應，因而提升了磁特性表現。
實驗顯示P3HT分子中C=C鍵結的π電子雲會與磁性奈米粒子中的磁矩產生交互作用，由拉曼光譜分析便可以得知，P3HT分子中的C=C伸縮振動能帶會受到磁性奈米粒子的影響，而施加外加磁場能更進一步提升P3HT分子與Fe3O4磁性奈米粒子之間的耦合程度，並從磁力顯微鏡(MFM)以及超導量子干涉震動磁量儀(SQUID)等物性分析中，更能清楚的看到P3HT分子摻入Fe3O4磁性奈米粒子後磁特性的提升，證實P3HT分子與Fe3O4磁性奈米粒子之間的自旋耦合會提升磁性薄膜的磁特性表現。

We successfully fabricate the thin films of magnetic polymer semiconductor composed of P3HT and Fe3O4 nano particles in efficient way at ambient temperature. The magnetic polymer semiconductor had remarkably ferrimagnetic hysteresis curve at ambient temperature, which indicated that there is an intense spin-coupling between P3HT molecules and Fe3O4 nano particles. After the horizontal magnetic field were applied on the Fe3O4-doped P3HT films, the magnetic signal on the surface of such films were more obvious through the observation of magnetic force microscopy. Through Raman spectroscopy analyses of Fe3O4-doped P3HT films, we observed that the electron coupling degree between the P3HT molecules increased after the application of the external magnetic field. It may be affected by the microstructures of polymer film or the existence of electronic coupling between π-electron cloud of P3HT molecules and 2p orbital electron of Fe3O4 atoms.
