Title: Microstructure and magnetic property of Co/Cu multilayers

Abstract

Co/Cu multilayers consisting of 120 bilayers, [Co(3.5{angstrom})/Cu(t)]{sub 120} with t = 15.8 {angstrom} and 18.3 {angstrom}, were fabricated on glass substrates by dc magnetron sputtering, and their magnetic properties were investigated. The Co layers in a multilayer are found to be an aggregate of ferromagnetic and superparamagnetic Co clusters dispersed in a Cu matrix. The present Co/Cu multilayers are revealed to be periodically modulated granular alloys with stochastic ferromagnetic structure.
