The transport properties of Co/Cu multilayers are calculated from first principles in the ballistic regime. Magnetoresistances as large as 120% are obtained in the geometry with the current perpendicular to the interface plane. The s-d hybridization is found to play an essential role in giving rise to this giant magnetoresistance effect.
