Abstract :
Co/Cu multilayers consisting of 120 bilayers, [Co(3.5 Å)/Cu(t)]120 with t=15.8 Å and 18.3 Å, 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
