Abstract:A series of CoZr(200 A)/& (t~~)/CoZr(200 A) trilayers with & interlayer thickness tAg in the range of 10-160 A was deposited on Si(lOo)-wafers at room temperature by using a magnetron sputtering system. In order to understand the dependence of the magnetic exchange interaction between ferromagnetic G&Zrldat.%) layers separated by nonmagnetic Ag layer on the tAg, we investigated the FMR spectra. The coupling strength increases with increasing tAg up to 20 A with a maximum value of 2.0 kOe, but decreases rapidly… 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.
