Abstract

Co-59 and Mn-55 NMR measurements have been made on a range of CoMn materials: dilute powder alloy, thin-film alloys, and multilayers. Our results suggest that in dilute alloys isolated atoms of Mn couple both ferro and antiferromagnetically to the Co host, with the latter producing a reduction in the magnitude of the Co hyperfine field of 17%. This reduction of hyperfine field appears similar for both the fee and hcp phases of Co. NMR on Go/Mn sputtered multilayers shows large changes in the hyperfine field distribution between a film with Mn layers of 10 Angstrom and Mn layers of 30 Angstrom.
