Abstract:The effect of carbon addition on the grain growth and ordering kinetics of CoPt film has been studied experimentally by sputter-depositing a monolithic CoPt-20 at.%C film of 24 nm. The carbon addition of 20 at.% to CoPt thin film in the form of CoPt (20 nm)/C n (4 nm) (n = 1, 4) significantly reduced both the grain growth and ordering kinetics. Reducing the thickness of the carbon layer, i.e. from n = 1 to n = 4, led to a much finer grain size distribution as well as to a finer grain size. The Monte Carlo simu… Show more
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.
