Abstract
We have investigated the giant magnetoresistance of artificial structures containing metallic Co/Cu/Co and /Cu/ spin-valves confined within insulating antiferromagnetic NiO layers. The observed enhanced magnetoresistance as compared to conventional all-metal spin-valves is interpreted with a semiclassical approach in which specular reflections at the metal/insulator barrier are included.
