This letter reports the modifications of spin-orbital coupling and magnetoresistance conjugated polymer upon deposition metal electrode based on organic light-emitting diodes poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylenevinylene]. We find that reverse bias yields a largely increased when electron-hole capture zone is away from as compared to forward with close electrode. The electroluminescence suggests deposited atoms enhance at polymer/metal interface consequently lead dependent magnetic field effects in semiconductor devices.
