Abstract :
have measured magnetoresistances in Co/carbon nanotube/Co spin-valve devices at 2 K. The resistance of a spin valve is normally lower when the magnetizations of the two electrodes are parallel. However, the magnetoresistance of our devices shows large peaks and dips, which represents complex nature of spin transport in the devices.
