Paper Abstract

In this paper we present the results of magnetization and magnetotransport measurements on Co/Cu superlattices with different Cu layer thickness, between 8 and 20 angstroms, grown in (111) crystallographic orientation. Cobalt layer thickness was kept constant at 20 angstroms, Al2O3 monocrystalline substrate was used with the orientation (11- 20). Tungsten 60 angstroms buffer layer was necessary to assure the correct growth mode. Careful structural characterization by different techniques was performed. Hysteresis loops and magnetoresistance was measured. Granular films structure and finite spacer grain sizes is discussed as a possible explanation of contradictory results on indirect coupling in the Co/Cu (111) system.
