Abstract
We present an experimental study of the transport properties of a ferr omagnetic metallic wire (Co) in metallic contact with a superconductor (Al). As the temperature is decreased below the Al superconducting tr ansition, the Co resistance exhibits a significant dependence on both temperature and voltage. The differential resistance data show that th e decay length for the proximity effect is much larger than we would s imply expect from the exchange field of the ferromagnet. [S0163-1829(9 8)51442-7].
