High resistivity magnetic films, such as reactive sputtered and Co-Fe-Hf-0, were applied to multilayered micro reactors for high frequency operation dc-dc converters. For a comparison, an amorphous Co-Ta-Hf film with good soft magnetic properties was also investigated. The micro reactor had the highest quality factor(the lowest loss) when using Cc-Fe-Hf-0 f i l m with the highest resistivity. In SMHz operation of dc-dc converters using these micro reactors, the ncy was obtained when

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.
