Superconducting proximity effect in a mesoscopic ferromagnetic wire
Superconducting proximity effect in a mesoscopic ferromagnetic wire
We present an experimental study of the transport properties of a ferromagnetic metallic wire (Co) in metallic contact with a superconductor (Al). As the temperature is decreased below the Al superconducting transition, the Co resistance exhibits a significant dependence on both temperature and voltage. The differential resistance data show that …
