Abstract :
Summary form only given. Ferromagnetic resonance (FMR) in electrodeposited ferromagnetic nanowires is studied up to 40 GHz using a micro-strip transmission line. Due to the simple geometry of these systems, the FMR can be described very simply when there is no anisotropy contribution other than the shape anisotropy. Tunability of the resonance frequency and the effective resonance frequency range are determined by the shape anisotropy and hence the saturation magnetization M/sub S/.
