Abstract

A large 'magnetoresistance' signal is observed in a system that combines a carbon nanotube as the channel for spin-polarized current with electrodes made from manganite, and shows that spin-polarized electrons are efficiently injected from manganite to nanotube and also efficiently transported through the nanotube channel.
