Figure 17.9. Maximum (saturation) value of the giant longitudinal magnetoresistance (GMR) in electrochemically grown Co/Cu multilayers as a function of Cu layer thickness. Cobalt layer thickness is held constant at 20 A per layer. The continuous curve is the corresponding RKKY function. (From Ref. 6b, with permission from the Electrochemical Society.)...

Thin films of cobalt can be prepared by nebulized spray pyrolysis using Co(acac)2 as precursor in a hydrogen atmosphere. The obtained films show brilliant metallic and magnetic properties. Granular, magnetoresistant cobalt-copper alloys of composition CoigCu82 and C050CU50 are accessible from Co(acac)2 and Cu(acac)2 mixtures under similar reaction conditions. ...
