Aromatic hydrocarbon macrocycles, which have a conjugatedπ-electron system, are potentially useful for variousorganic device applications, although there have been no attempts to apply themto organic spin valves (OSVs). Here, we studied OSVs with[6]cyclo-2,7-naphthylene (CNAP), a type of aromatic hydrocarbon macrocycle. OSVstacking structures ofCo/AlOx/CNAP/Ni80Fe20 withdifferent CNAP thicknesses were fabricated, and the transport properties of theOSVs were measured from 300 to 5 K. A magnetoresistance of approximately 1%-2%at 300 K (4%-6% at 5 K) was observed for 15-nm-thick OSVs, showing the potentialfor organic spintronics based on aromatic hydrocarbon macrocycles
