Ferromagnetic resonance studies of electrodeposited Ni/Cu multilayers

The magnetic properties of Ni/Cu multilayers, prepared by the electrodeposi tion technique, have been systematically studied by magnetic measurements a nd ferromagnetic resonance (FMR). The Ni thickness dependence of the magnet ization and magnetic anisotropy is discussed. The FMR spectra were obtained with an applied magnetic held parallel and perpendicular to the film plane at 300 K. The FMR linewidth of the granular multilayer is rather broad, wh ich is attributed to some roughness. From FMR, a positive Value for Ni/Cu i nterface anisotropy has been obtained.
