We report room-temperature spin valve effects in Alq 3 -based vertical organic spin valve (OSV) devices with direct interfaces between Alq 3 and the bottom and top ferromagnetic electrodes. In contrast to conventional OSVs, where the top electrode is directly deposited on top of organic layer, we use indirect deposition method. We find this method can significantly suppress the penetration...
We have embarked on studying magneto-transport response of organic spin-valves made of evaporated Alq 3 spacer sandwiched between two ferromagnetic (FM) electrodes with spin-injecting capability. Recently, we have fabricated and completed studies on organic spin-valve devices using half-metallic manganites as one of the spin-injecting FM electrode, which have shown giant magnetoresistance...
