Abstract
We have investigated the giant magnetoresistance of artificial structu res containing metallic Co/Cu/Co and Ni80Fe20/Cu/Ni80Fe20 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.
