Abstract:Serious selective evaporation exists for CoCr films during low rate electron beam evaporation (LREBE), and causes composition discrepancies so that the ratio of x(Crwt%) of the film to X( C1.'I'1t%) of the ingot lies within a ra..'1ge 2.0-3.0. Relations of x with other experiment's factors are given. The reasons for the selective evaporation and composition discrepancies are discussed. On the bases of measured results and micrographs, comparison between the microstructures and magnetic properties of good and p… 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.
