Abstract
This study reports the highly deleterious role of small amount of carbon on the structure and magnetic properties of giant magnetoresistance NiO-Co-Cu-based spin valves. Controlled incorporation of 1-3 atomic % carbon in the Co/Cu layers, resulting in the formation of pinholes, and associated degradation of structure-sensitive magnetic properties. In addition, carbon promotes the formation of a high density of stacking faults in the Co/Cu layers, with carbon nanoprecipitates forming in the vicinity of the stacking faults. Results have implications for other multilayers and magnetoelectronics devices.Citation
