We have monitored the structural evolution of Co(tCo)/Cu(4xtCo) multilayers when tCo ranges from 12 to 2 Å. The investigation has been performed by studying their magnetization and giant
magnetoresistance, since these properties are complementary in providing information about the structure of the magnetic species into the samples. In particular, in the intermediate range of
thickness, we observed no correspondence between magnetic and magnetoresistive behavior. Finally, at sufficiently low thickness, the samples exhibit noninteracting superparamagnetic features.
This kind of evolution has been ascribed to the progressive fragmentation of Co layers
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
